Hello. I’m making game, and for it I made one test character:

(Don’t look at his face, I just got lazy and did decal instead of mesh)
For his arms and legs I used IKcontrols, but they work diffirently on server and client

(Server) . . . . . . . . . . . . . . . . . (Client)
Important to note that his feet can just rotate randomly, not only like this.

Can someone tell me, how I can fix this weird bug?
