Well, for me lately there are only two maps that cause consistent crashes, field_by_the_river and castle 2; every single time they come up, the game crashes about when the first player model comes into view. All other maps play fine, apart from the very occasional crash. I always vote against those maps for that reason
I don't know what the error message is, since I play from linux with wine, it comes up with a blank error message box (fairly common with error messages when running in wine).
This might be hijacking the thread for an unrelated issue, since random maps and snowy village work fine. The problem started not long ago, I think around about in the .61X range; before then all maps generally loaded fine.
We didn't only meant that snowy village or random maps crash often for us. When playing a game with about 30 players and it changes to one of these maps it takes about a minute and we are down to ten players...
So as you said Vornne, your problem seems to be something different.
