2 visual character of the same player on top of each other

1 to 2 times per hour in a multiplayer game, I was able to see the other players as if they had 2 character models of their character stack on top of each other. They would both move around as if they were one entity, but their animations would be slightly out of sync, allowing you to see both models. The odd thing is one of the model would be not wearing any gear or weapons, and the other would be the normal visually equipped model.

You can see it in the screenshot here. The character affected by the bug is the one named Momentaryinfinity

Just a visual bug, but probably something worth looking into.
