having issues with players losing guns in stacks. when stacked they disappear into 1 gun. Only does this on guns found in barrels etc, when its guns from my f1 panel it doesnt do it. Help?

All my stacked weapons are still stacking as normal (200) whether i get them from chests/barrels or airdrops. Might be something in your config or another conflicting plugin that is doing it.
When the weapons stack in inventory they show as "a weapon" and only show the amount when you click on them (which shows division bar/amount) or when in backpack whichs shows amount of each stack.
