Crash on Overlan Map SOZ

[Vizjun]

hey can any one help me with this issue, im playing a lan game with my bro and when we go to the overland map he will crash, any ideas?

Any particular map area? Location? Time in the game? Situation? Spells active?

Any error message you're getting when this happens?
