Character in different positions locally than to other players?

So this is a very weird bug that is consistent, but I have no idea what causes it.

Players in my game will randomly be 10 studs away from where they actually see themselves. I have no idea why this happens. I could only assume its my sprint script (which is local) or my chain/backpack script which cframes a model onto the players torso and welds it, but besides for that, I have 0 clue.
