I've been experiencing this sometimes, and it's frustrating, when i ride in the horse and sneak to get out of it, my controls reset back to normal, then im going to customize it again to the place where the buttons im comfortable with, but then i ate golden apple and again it reset, i ride a boat and when i sneak, damn it reset again, it's so frustrating that every time it reset, you going back to customize it again, please fix this bug not only for me, also for those people that experiencing this kind of bug too.
