Just started noticing this tonight, and i've tried to replicate it with all possible combinations. It seems that whenever we hook up to anything with the winch, the game freezes and then crashes to desktop.
I've been able to replicate this in single and multiplayer games.
--Used only certified mods, still crashed
--Used uncertified mods, crashed (expected given they aren't certified)
--Used a completely mod less game, still crashed
All of this seems to happen when you try to winch to another vehicles or to a tree.
Sounds like this came up about a year ago, according to an old steam forum post. It seems to have reared it's ugly head again
Anybody else experiencing this issue? I've done a complete reinstall of spintires to no avail
Post up any possibilities you got guys
