On floor 3, I had chosen the draconic lair quest where you need to erase a seal to open the exit. Same thing on floor 6, except that I had to flee to the top floor before completing that quest. Now the floor 3 exit is also sealed, citing that I haven't finished the quest, but no new seal/dragon have spawned. I don't have an elevator access to bring me past floor 3 so I guess this save is stuck for now

Sorry for bothering

Can you activate debug mode and create a save code?

You can also use it to salvage the save by force unlocking the stairs, but it will help me find the problem if you can get a save code.

To enable debug just boop the gag in the main menu and then go to the pause screen
