Messed up gun hand animations

I found a bug which seemed to happen I think when someone revived me and my hands were suddenly scrunched up and the gun was aiming to the left. This happened on both the pistol and the main gun when I switched between them. When I died again, and someone revived me it fixed itself. Unfortunately, I didn't manage to screenshot it.

I can't find the post now but someone else had noticed this bug too.
