Specific objects not moving in animation.

I have a player model that has weapons added to it in the editor. I have created an animation of the player reloading a weapon. In preview it looks fine. In game, none of the weapon’s bones move. I can’t seem to figure out what the problem is.

In game:

I figured out that it wasn’t included in the avatar nor the avatar mask.
