Turning in one direction while in the Island Lake Swamp in Michigan

I've encountered a serious issue while traveling through the Island Swamp where I saw driving one of my rigs into the swamp and learned that I couldn't control the steering nor could I do into the direction I wanted to which was VERY frustrating.

I ran into this too. I tried it with the Tayga 6463 and the CAT CT680 both with no steering in the swamps, but had no problems on other maps that I've tried.
