Missing entrance to Maggot Lair Lvl 2: D2 Res

I have cleared the Maggot Lair level one multiple times and there is simply no entrance to lvl 2 on my map. It isn’t the well known “door bug” where they’re difficult to open. There just isn’t a door to head down, so I cannot progress in the game. I’m on normal difficulty, so I can’t change the difficulty to reset the maps. Please help! I put 18 levels into the character and i’m now stuck.

Try changing the graphics to the old style. I’ve seen these bugs a few times and switching to the old graphics made it visible.
