Just posting to confirm I am also having this issue so it's not an isolated incident. The extra wrinkle is that my most RECENT session/character (4 person multiplayer file) loads just fine. It is my newest playthrough but NOT my most recently saved file. I loaded up an older file with 20-25 hours on it on Tuesday the 24th just fine and saved it, but that and my other file with 30+ hours now CTD. Tried the same stuff as Danny except a full reinstall. Would love to see this addressed as starting new files for both my 30+ hour single player and 25 hour 2 player does not appeal to me. Thank you for any help.
