*still unanswered* Game moving gun after pausing

Hi i reimported a model and changed a few things and now when i pause it offsets the gun. I have no idea what i did ive been looking at it for hours and still nothing.

the gun code is a little broken. im trying to make it so that if the starter gun checkbox is true, put the gun in his hand and parent it to the wrist.

Remove the rigidbody off of the pistol. Game then behaves fine.
