Only happens for the guests never for the host.

When Wisconsin is hosted, sometimes the game would crash for the guest every time he tries to join the game. The game would load and you see the garage and at this moment game crashes.

Rejoining doesnt help - you would crash every time until the host changes the map to one of the old ones from prior updates. Alternatively the host can rehost Wisconsin and it will be magically fixed (or not, its random).
