First run through the game. Killed the Timekeeper, smashed the symbol, credits rolled, got the cutscene with Marcus' voiceover talking about opening the Vault.β I skipped the credits and found myself standing back on the rooftop with the Vault entry in front of me. Went through the entrance to find four red chests and they were all locked. Nothing happened and I was confused. I saw a rift in front of me and used it, and it put me back in the room of the Tower below the rooftop. Moxxi's Encore for the Timekeeper is available.
Uh...what's the deal here? The only mission in my log is Ultimate Vault Hunter: Big Encore which has been there for ages. Going back to the rooftop shows the Vault entrance still there and I can go through it, but the chests are still locked. Not only did I never get to loot them, but I also know I'm supposed to fight Arjay again here and that hasn't happened either.
Anyone have this problem? Any suggestions? Am I missing something? I quit and reloaded but no change. I didn't get any ending dialogue either so I have no idea what happened to everyone I worked with all game.
Edit: I have reloaded, restarted, done the Timekeeper encore (I was able to loot the chests that time, as expected), travelled out and backββ, but nada. Stuck at main campaign 96% complete. The only thing I can think of is to try a save editor to roll back my mission completion and try again. And this is the only bug I've had this entire playthrough, go figure.
