Trying to iron out bugs on Frog's Weapons, I found another bug (that might have been reported before), that when you hold a weapon empty of ammo and run over a ammo pickup, you load the wep, but more then likely will deplete your reserve loading your wep.
To fix, people can quickly put the weapon away while running over the ammo pickup, thus gaining the ammo before you reload and stopping the odd 'losing ammo to reload on empty' bug.
