Weapon Loadout not saving (if no muzzle)

Hello, 

I had the same bugg during the beta :

If you don't put a muzzle on your weapon, the loadout does not save and you have to do it again at the start of each game, and its really annoying.

Can you plz fix this, bugg was already here in beta and we already made feedback about it during beta.

Thanks.
