Crashes after turning fan on in blast pit

Not much to say to it. Whenever I turn the fan on in Blast Pit and the fan starts to rev up, the game stutters and crashes. This has happened three times in a row, in exactly the same way. It also crashed in that same room when opening the door at the top, but that was only a one-time occurrence.
