Title. Trap/locked treasure room in Court of the Magi. The tentacle doors locked behind me and I opened all of the chests except for the opulent one which remained locked. No enemies spawned despite me running around for 5 minutes trying to interact with stuff. Had to restart game.
Edit: it’s the room with the magi bosses. Bugged when I used the elft hand side door. Right hand one spawned them correctly.
