So, I left my game running overnight like always, and when I came back a machine of mine had got backed up so I fixed that, and right after, My sprinting started glitching out. When I run, I cant top until I hit a player, mob, or block!!! Has this Happened to anyone else? If so, how do I fix it? Please Help!!
