4 player crash

Had a REALLY frustrating crash last night. 4 player PC game on darkness difficulty. I was Aladdin. We were on a great run when just as we killed the 3rd act boss my game crashed! The rest of my group stayed but died on the 1st wave of baba yaga since they were shorthanded. I'm done with this game for a while. Please fix these bugs and multiplayer difficulty scaling.
