My friend and I have been experiencing a persistent issue which prevents us from joining each-other's game. When one hovers over the others game, a message displays which indicates that the game or mod version of the host is incompatible with that of the person who hovered over it. I can't attribute this incompatibility to any cause as we both verified that we installed our games correctly, and with the 8.0.1 patch. Does anyone know of this issue and/or knows of a way by which this issue could potentially be resolved?
