Bug Selecting a weapon while already having one equipped takes ammo from your inventory

[Chezburger]

If you equip a weapon, then attempt to swap to a weapon that takes ammunition, you cannot swap weapons (intentional, I believe, which is okay) however, ammunition is taken from your inventory in the process.

As an example, I had my glock equipped with hotbar 1 and pressed 4 on my hotbar, which is what I have my taser bound to. Upon doing this, I obviously still have my pistol out, however my hotbar pops up briefly as if I had selected my taser. Upon checking my inventory a random amount of ammunition for that weapon will be missing.

To further clarify it appears that doing this loads the weapon. So it's not going missing, but it's a different way of loading weapons without actually clicking on them in your inventory screen.
