Stuck in Gorbat Pride

[MajesticGrey]

Hey there!
I have a problem: I am in the second level of Gorbat Pride, but I am unable to proceed to the next level.
Both levers are pulled, but it will not open, and, unless I am mistaken, I need to finish this to continue on with the game.

Extra info:
I do not have probability travel
There was a vault on this level (I completed it... level 92 multi hued wyrm thing)
I pulled both levers only after completing the vault
I have killed everything the level


This actually happens on another pride, but there is some weird explosion glitch there, and I already killed the boss so I'm not too worried about that one.
