Having the same issue. Crash every time I try to connect to a LAN multiplayer game my SO runs. We have been playing for 100+hrs now and just encountered the problem last night. Few comments and things we have tried.
- I can load and play my own game
- Can't seem to log into other multiplayer games in the lobby (never tried in the past either)
- Reinstalled DOS2
- Tried the Arena trick
- The error message sometimes throws a C++ error message but not consistently
- We tried previous saves and same issue happens
Any help would be great. Love the game and would hate to stop now!
