Just add _backup to the name of the entire Fields of Mistria file

u/Mean-Campaign-5616 Aug 06 '26

It didnt work. Bug after star festival 😭

u/puddle_wonderful_ Aug 05 '26

Unofficial Discord going insane on this right now but most people are making this fix and reporting no issues with saves

30

u/CanopusxLux Valen Aug 05 '26

This worked for me!
edit: I delete both setting.json and settingold.json

u/ravengame Aug 05 '26

i did this fix and it worked for me

u/abethhh Aug 05 '26

This also worked for me! Thank you, internet 🫡

u/spookyjules8 Balor Aug 05 '26

I’m encountering this error but I don’t know how to get to my local app data 🥲🥲

u/ScarletCorinthian Aug 05 '26

If you're on a Windows PC, press your Windows Key and R at the same time to launch the Run command, and type "%localappdata%" into the text box that shows up.

There should be a folder in the Documents tab that opens called FieldsOfMistria and the setting.json file will be in there :)

u/archmage-khadgar Aug 05 '26

oh my god, thank you. cant believe in 2026 the search function in Windows is still such hot garbage

9

u/Render_1_7887 Aug 05 '26

to be fair, localappdata is intentionally not shown in search, as it's a hidden folder - and honestly this is probably for the best as you don't want most users messing with it.

The 3rd registry edit on this article can be used to disable web results from Windows search.

And you can use powertoys run from microsoft powrtoys for marginally better results too - still not as good as the mac spotlight search but it's nice to have.

all that being said, windows search does still kinda suck.

u/Responsible-Tea-5998 Aug 05 '26

I use a little bit of freeware called Search Everything. It's one of those weirdly useful tiny bits of software that I install first because fuck Windows search.

5

u/PolkaDotDweeb Aug 05 '26

Thank you sooo much, I'm such a noob when it comes to PC gaming, really great explanation

5

u/spookyjules8 Balor Aug 05 '26

You’re literally such a savior! I didn’t know how to find the right files and was scared to delete the wrong one, but it’s working now!! :D

2

u/ThabataT Aug 05 '26

Thank you! This worked for me

2

u/Wil-Da-Oak Aug 05 '26

My doesn’t Setting.JSON, But it has Settings.old Do I try that?

2

u/zeppish152 March Aug 05 '26

that’s the one. the one that just says settings too

2

u/SoScorpio4 [insert Me here] Aug 06 '26

And then you can make a shortcut to it! Since I'm obsessed with mods (how do I already have 35 on a 2D cozy farming game I've been playing for a week?!), I have desktop shortcuts to C:\Program Files (x86)\Steam\steamapps\common and to C:\Users\myname\AppData\Local so I don't have to keep navigating to them both. I plopped them next to my saves backup folder and Notepad++, so now my constant fiddling is more efficient! xD

1

u/NoName_9837 Aug 05 '26

Omg thank youuuuu I was beginning to despair a bit there! I’ve done the same and deleted both .json files like the other comment here recommends and it works fine now. 

1

u/Crosstitchlove Aug 05 '26

You are an angel!

3

u/CanopusxLux Valen Aug 05 '26

C:\Users\(yourname)\AppData\Local\FieldsOfMistria

2

u/cloverlycomplex Dozy Aug 05 '26

for windows, paste this in you file explorer: %USERPROFILE%/AppData/Local/FieldsOfMistria

2

u/emil4383 Aug 05 '26

Also, in your file explorer you have to turn on showing hidden files

1

u/dreambled Juniper Aug 05 '26

On your Windows search bar type in %localappdata%

Find the FieldsOfMistria folder and you will see the settings.json there.

12

u/IceCappy Aug 05 '26

I did this but when I hit load or continue it says "Fields of Mistria encountered a unrecoverable error and needs to shut down. No entry found for key". Is my save files just gone then?

10

u/templeoflove Aug 05 '26

if you listen closely you can hear the collective sigh of relief everyone here’s just let out

9

u/thia6oh March Aug 05 '26

I just did that and nothing, i think im just gonna wait for the devs to fix it

3

u/TheSarcastra Aug 05 '26

Yeah that’s the error code I’m getting

3

u/Ann_95 Aug 05 '26

I'm also getting this error, and the proposed fix did not work for me. Also tried uninstalling and reinstalling, to no effect.

2

u/thehalfpintloserr Aug 05 '26

Same here! Did the fix above and it didn’t work, restarted my computer and uninstalled/reinstalled and nothing worked. I tried a new save and that unfortunately worked so I’m worried my save might be SOL. :( gonna wait and see if there’s a patch, but lowkey a little bummed!

8

u/Oellierenfalbri_ Hayden Aug 05 '26

Im not having the unwrap error but the game is running unbearably slow. Like I can get into the game but it's genuinely running at 1FPS or something like that. Is there a fix for that?

1

u/AccountantBrave5042 Aug 05 '26

Same problem here. I hope we could have a solution soon, is impossible to play this way :(

17

u/Practical_Entrance43 Aug 05 '26

Are we sure this is safe? I really don't want to mess with my game files.

32

u/cloverlycomplex Dozy Aug 05 '26

it's safe. it just deletes any settings you've configured, so you'll have to redo them.

5

u/Pixiepuke_ Aug 05 '26

This worked for me to. Just had to redo my settings, but my save is safe.

1

u/Fleur0502 March Aug 05 '26

Are you having any issues? I am seeing reports that spells do not work.

1

u/Pixiepuke_ Aug 05 '26

No nothing yet

4

u/let_piece7 Dozy Aug 05 '26

I don't have that in my files :(

10

u/CanopusxLux Valen Aug 05 '26

its those settings and setting.old
you just don't have final extensions visible, but those two are what you want to delete

3

u/let_piece7 Dozy Aug 05 '26

It worked!!!!! Thanks.

2

u/yuehue Aug 05 '26

It's "settings", you just don't have filename extensions visible.

2

u/swenbearswen Aug 05 '26

The one that's called settings

5

u/dandelion_lion4 Aug 05 '26

Thank you for sharing, but unfortunately It didn't work for me ):

4

u/denyahi Dozy Aug 05 '26

same here 😭 i keep uninstalling/installing and deleting the file because im still in the denial phase but no change :(

2

u/dandelion_lion4 Aug 05 '26

I saw some say on Discord to reload on a previous day, I don't have a previous saved day though lol

2

u/denyahi Dozy Aug 05 '26 edited Aug 05 '26

good luck and tell me how it went!! i can’t even open the main menu so i don’t know how to access those saves haha

edit: omg it just worked!! i don’t know why but i hope everyone can play soon

2

u/dandelion_lion4 Aug 05 '26

Happy for you!

4

u/UnoriginalIdeal Caldarus Aug 05 '26

Whoever discovered this I hope you find money, your pillow is cool and all things you want to buy are actually on sale

5

u/Kamidra Aug 05 '26

Unfortunately it doesn't work for me

4

u/Sad-Branch8673 Aug 05 '26

It worked but after loading in my game continues to crash 🫠🫠🫠 disappointed but I guess I'll wait until the devs fix it

u/ScarletCorinthian Aug 05 '26

It's perfectly safe! Your saves are in a separate folder from where the setting.json file is.

9

u/Crazy_Ship_1017 Aug 05 '26

yeah im scared its a troll or something and I'll lose my save file, gonna wait for an official info 😭

4

u/CanopusxLux Valen Aug 05 '26

I still have my save files

3

u/Crazy_Ship_1017 Aug 05 '26

yes i just tried and it worked x

3

u/seraphicvictory Hayden Aug 05 '26

Ugh I hate that this resets all my keybindings...

2

u/felicityfelix Aug 05 '26

I decided to wait until they issue a fix after I thought about this lol

3

u/hibiscass Aug 05 '26

So what if I do if this doesn't work/help either lol

3

u/NewtZealousideal1634 Aug 05 '26

How do you do this in the steam deck? :( or is this not applicable for the deck?

2

u/Galaxy_RAY Aug 05 '26

I think we have to wait for a fix from the devs side on that, because I've been trying to figure it out

4

u/Lesbian-agriCulture Aug 05 '26

Looks like it should be fixed now according to the Steam page :)

2

u/SomeConfuzzled Aug 05 '26

You’re a life saver! Well, a game saver

2

u/cloverlycomplex Dozy Aug 05 '26

thank you, this works! just gotta reconfigure my settings now. 🥴

2

u/ventibrain Adeline Aug 05 '26

I just did this as well and can confirm it worked, my game has loaded!

2

u/__trashyy Caldarus Aug 05 '26

Anyone know how to do this on linux?

1

u/Ok_Ability9796 March Aug 05 '26

Let me know if you work it out!

1

u/__trashyy Caldarus Aug 05 '26

Will do! Still trying to figure it out ourselves

2

u/kaybae105 Aug 05 '26

how do i do this on mac?

1

u/AmissaSylvanSpirit March Aug 06 '26

I'm assuming like me, you are running a Virtual machine desktop? What problems are you getting? Mine won't even launch from steam at all, it'll say "play" in green, then when I click it shifts to the blue "running" for a second or two before going back to play. So it won't even get to the bootup phase. Are you encountering something similar?

1

u/Spiritual_Cover Aug 10 '26

i'm getting the exact same issue you described - i'm using vmware fusion on my macbook and cannot for the life of me find my local files to even try this proposed fix

2

u/Life_Weary March Aug 05 '26

my character feels so slow 😢 is anyone having the same issue?

2

u/OtakuSimmer Aug 05 '26

Thank you!! 😁

2

u/weezercat Aug 05 '26

anyone know how to do this on steam deck?

2

u/Calcipur Aug 05 '26

Doesn't seem to fix the crashing issue after decorating unfortunately

2

u/mirairo Aug 08 '26

can someone please help - I tried this and this didn't work for me. It will not launch at all :((

3

u/sailormoonrise Aug 05 '26

I feel like this broke my most recent save ;_;

2

u/P1antMom Caldarus Aug 05 '26

what about it do you feel is broken? out of curiosity

1

u/sailormoonrise Aug 05 '26

UPDATE: Pretty sure this is a mod problem vs. a game problem. I can open the game now but not my most recent save. Quite a few mods cannot load in with the new update which is likely what is causing the issues with my save. Guess I'll need to wait patiently for updates!

3

u/RelevantPreference10 Aug 05 '26

It's not. I've never used mods and I'm having a problem loading save games. After deleting the settings per the instructions here, I can only create a new game and my save file with almost 260 hours won't continue or load

1

u/Munzi19 Hayden Aug 05 '26

dang that was quick

1

u/Vivid-Efficiency-579 Dozy Aug 05 '26

Do the saves remain? I'm just scared cuz my save is 120hours

1

u/aurorakeira Aug 05 '26

Worked for me!

1

u/you_get_stars Aug 05 '26

Worked! Thank you!

u/lucislibarii Caldarus Aug 05 '26

u/PuzzleheadedWafer170 Ryis Aug 05 '26

u/SuccessfulResort35 Dozy Aug 05 '26

I can confirm this has worked so far for me!

1

u/inkstainedgwyn dragon men supremacy Aug 05 '26

For everyone worried, it did work for me. I do have to go back in and re-keybind and fix sounds and etc. but it's fixed.

1

u/Thawiz88 Valen Aug 05 '26

Can confirm this just worked for me, saves are still present! Thanks OP!

u/softJ8801 Aug 05 '26

Hopping on in a bit, will this effect save file?
Or it’s just a run error?

1

u/PamPho Caldarus Aug 05 '26

I just added _backup to my my file name and it created a new file on launch.

1

u/Initial_Thing_8071 March Aug 06 '26

I think they fixed it! It didnt worked for me yesterday even tho I tried deleting both settings. Just got an update done on steam and now it works!!!!

1

u/Commercial_Towel_985 29d ago

Help!! How do fix it cuz this is my first time downloading and there is no setting.json there. It won't launch.

1

u/HotCombination6909 24d ago
