There is no fix for this problem, this is a game loading problem scenary. Just restart a new game if the carriage become crazy, you lost nothing, this is the begining. I have 168 mods installed, I do not read stupid arguments to uncheck ALL and trying to find WHICH ONE may cause this, mods cause the bloat in a save, nothing else. Even ppl talking about refreshing rate of this 60hz is a stupid urban legend, a game can load without a screen guy, an OS can load without any screen, this is a DD loading, the screen do not affect such a thing on a game in all over the world, are you crazy?? I restarted a new game after seeing this crazy carriage scenary, and I let my f***in 168MODS installed and ALL CHECKED and IT WORKS, I test another time and it works, and sometime, the carriage become crazy, yeah, it's happend, same in real life if you drive your car, all is fine every days and ONE f***in day you have a car crash. The problem is a badluck problem, just restart untill it done.
