WHAT ?! Big Bug SIms 3
Guys help me pls...
it's been over 15min that my game is like that but Why ? ... you know why?
You probably have some bad CC, maybe a corrupted texture. That usually causes that kind of issue. If you added anything new recently try taking it out and restarting and see if the issue remains.
Is it with every horse? Did you download something new?
Try changing the tail/tack, this usually helps. If not, clear the caches & re-load the game and see if this solves the problem.
