If one particular map has been identified as causing player PC or server crashes, Find Potentially Bugged Objects of a Map by Process of Elimination
I'd encourage you, if you have a specific area that you crash in when you transition to it, to try deleting all the content from the area, rebake, and try to enter the area again. I'm talking deleting everything in Area Contents, including triggers, waypoints, lights, etc., plus all your scripts. If you still crash, then you know the problem is in the game engine coding or the network. If you don't crash at that point, then you know there's a bug with one of the area content items. At that point, I'm sure we'd all appreciate if you systematically deleted different content items until you find the one that caused the crash, in which case we can inform Obsidian specifically where the problem is and get a fix.
