waterpipe shotgun only reloading when both shells are in inventory

when trying to reload a waterpipe shotgun, it used to normally take shotgun shells… but theres a problem now that only lets you reload if you have handmade shells in your inventory…but it will only use up the normal shotgun shells, so you will need those in your inventory too or it just wont register a shell being put in even though it goes through the entire reload animation (which you can do again and again because the ammo counter stays at 0) which, btw, still shows shotgun shells being ejected in it. if you dont understand, I’ll post up a video.
