A friend and I were trying to set up some multiplayer and sadly keep running into crashes. We are both using OS X and Steam.
Steps we took (sorry that we can't narrow it down):
- Start a new multiplayer game.
- Add four characters (two each).
- Kill the bugs in the basement.
- Go to Pomab's Emporium.
- Both talk to the store owner.
- Buy some stuff (seems to be repeatedly buying arrows).
Any suggestions for how to fix would be great, IWD is a game both of us have been looking forward to playing co-op in for some time.
