Just had this happen to me. Seals on floors 10 and 11. Went back to floor 10 to look for a shrine for a cursed restraint I had, and the exit stairs for 10 locked again.
Yikes! I had hoped I put a fix for this in the latest version, have you updated yet?
Yes, although my save was initially from a previous version, and I was on floor 11 when I updated. Not sure if that would affect the fix.
