I am having huge trouble with Runtime errors with the game, as well as some of the game textures turning white after awhile. I have quite a few modded maps & trucks. If needed, I could upload my PC specs. Thanks.
Same problem sometimes, most of the time when scrolling and choosing trucks in MP lobby.
Do you have the memory limit fix installed? If not, I'd bet it solves your issue. Check out Spintires.NL as I'm pretty sure that's where I spotted it most recently...
