Bugs

 * Ammo boxes: It seems if a player cannot carry more than 100 surplus small energy cell charges. If the player buys two or more boxes, only one will show up. If the player buys one box, drops that box, picks up the cells, and buys a second box it will have the same effect. Problem may apply to other types of ammo.
 * Ammo boxes: If the item was purchased through a vendor, the player may have to drop the ammo box onto the ground (through the Pip-Boy) and pick it up off the ground to receive the ammunition contained inside the box. *Confirmed* [This has been fixed in the 1.2.0.285 patch (PC)]
 * Occasionally when switching between types of ammunition for a gun, the loaded ammo may become "stuck" and not allow you to switch. To correct this, drop all ammo of the currently loaded type. The gun should then switch to the other ammo type and you can pick the first set of ammo back up. *Confirmed*
 * In reference to the above statement, you cannot change ammo types (by hitting up on the D-Pad), when the weapon is holstered. Additionally you might not be able to change ammo types via pip-boy on an equipped/holstered weapon.  You can unequip in the pipboy, then change ammo types.
 * When using ammo that modifies a weapons damage, all viewed weapons show equally modified damage regardless if they can even use the ammo. Using ammo that does 1.5x damage will show a grenade doing 1.5x damage on mouse over.
