im walking too close to a friend of mine, and i changed my stance (went prone/crouch/stand up), it appears to my that my character is, for example, crouching, but my movement speed is like i was standing up, so the character moves too fast while crouching, as if for the server and in everyone else's screen, i was standing up. It can happen also the other way around, like in my screen im standing up, but my character movement speed is like im crouching, going crouch or standing up doesn't seem to fix the problem, only invert the situation, but i manage to debug this by going prone and standing up.
