Laboratory Crash

[Ambrosia]

Okay, so, I've verified the integrity, and it came back fine, no files missing. I tried opening the save again, and there're some oddities to the issue. I can be in the laboratory fine, no crash. I can pull up the lantern, look around, walk forward while facing the right wall, and light the torch on the wall. A moment after I turn away towards the stairs, the passageway below collapses, or something, and then the game crashes. I don't know if that helps to diagnose the problem, but it's something, right?
