Lifthrasil: Are you playing the director's cut and are you blocking outgoing connections?
AB2012: I don't know what everyone else is doing but I just tested it up until the first hack & takedown in the first mission (as was claimed as a trigger) and had no problems, and that's saving beforehand and testing it twice first with being just blocked by running the firewall as a "whitelist" (block by default, allow by exception) and second by completely disabling network interfaces in Device Manager and had no crashes in either case. I also tested the
"interact with all items in the start room" (probably referring to the
6x items you interact with to unlock the Old School Gamer Achievement) and that didn't crash either. I'm using offline installers, Galaxy has never been installed. If there's a problem then it's got to be something that doesn't affect everyone equally. People affected should post in more depth as to what they're doing (eg, using Galaxy or not). Maybe even upload a game save right before the crash.
OK. Thank you for testing it!
