OH LOL sorry then xD
sorry, I only sort of know what you mean
it works like this: you got max 100 shotgun ammo
but if you got 99 and pick up a box with 20
then the 19 other shells are not lost
and then you have 119 ammo
but you cannot pick up more until you fall below 100 again
so I wanted a system that is fair - but it ended up confusing 😕
(works in a similar way for health but it counts back if you got more than 200)
