Could you go into: C:\Users\<username>\AppData\Local\RotW\Saved\Crashes and if it exists, zip up the crashfile and email it to: methodiar@gmail.com
I'll look into it. I don't know what causes it. Some people never get it, others occasionally and a few get it all the time. I suspect it might be a hardware configuration, but the crashlog should help.
I would recommend updating Windows and your GPU drivers first though and seeing if it still crashes.
So, I'm using one of the latest Unreal versions for the game for the procedural generation stuff. A common UE issue is the newer versions have incompatibility with older GPU drivers, which has a habit of causing "Unhandled Exception: EXCEPTION_ACCESS_VIOLATION". I believe it's trying to find something in registry which has moved between UE versions.
It may not be whats causing this bug though, but as it's a common issue, it's usually best to rule that out first.
