In my first try of the creepy crypt in adventure difficulty. I skipped a goal and i progressed in the dungeon, i got in front of an exit with a gate. After killing all the mob near the gate, the gate didn't disappear but i could take the exit. After that i couldn't go back in the crypt. I managed to get to the end off the level but I couldn't exit it. I could exit the level only with the pause menu.

Here's a screen and a video of the situation after i took the exit
