So yesterday I was playing the latest and greatest DLC and the game became slow and stopped responding. Managed to ctrl-alt-delete and stop the game. Started the game up fine again and no probelms. Several more starts and stops, no problems and then finally one hard crash to the desktop that resulted in some sort of memory not allocated error notice (unfortunately the desktop was in a bad state and I could not copy the message. Stopped playing for the day. The next day (today) I started up the game to find that I have lost all my characters except the one I was playing the day before. I have steam cloud enabled yet nothing will sync up. Any advice would be appreciated.
edit: The game seems to be really unstable in the area of the Subconscious in the new dlc content. I was just playing through that area and realized all my progress through that area was not present in fact this is the area where the crash happened. The game becomes very unstable in this area when playing it.
