The lack of traction while driving on rocks just plain sucks. Adding the rock traction mod fixes it but it should be addressed by the dev's. It's a simple fix adding the friction line to the rock xml page. I'm really hoping this is seen and addressed. I always add some crawling to my maps since a big part of mudrunner and hopefully snowrunner is hardcore trailing and rock crawling.
The game is definitely coming along. Looking forward to the future of it
