Hello unholyjoe,
sorry that i answer late on this but i tried to get more information.
The server we use is rented at Gportal. It is a pregen10k map. I have no access to server settings. i made screenshots from 2 crashes.

Nothing like this happened when I was hosting a game for my husband and one of our friends.
My private map is a medium one if i remember correctly.
thank you 🙂
