I changed that and my save game is still fried, and this is the only map I have that isn't working. Not sure what other conflicts the patch caused. Vehicles will turn on, but not move. As soon as I tab to a different vehicle, the entire game freezes up. Again, only on this map.
I just got back from vacation a few hours ago, I have the terrain shader fixed. I have noticed a few other problems with crops, that I am going to look into before posting a hotfix.
I so far found one mod causing a conflict. Exhaust Extension...it started throwing a LUA error on me after I downloaded Missouri River Bottom. Loaded Midwest Horizon without it, and seems to be working now.
