The Ammo Support Drag Onto Weapon Item Weapon Templates also has another option I forget the name right beside them, telling which item to craft/spawn and replace your weapon with as soon as you drag an ammo onto it.
So using in game ammo, and deciding to change how in game ammo works, are 2 completely different trains of thought. The ammo itself should actually tell your new custom bow, to revert to the stock standard Vanilla bow through their preferences. But the ADK also has the same ammo drag preferences inside the weapons as well, I would hazard a guess that it is simply an inheritance situation though. But as the ammo will tell your NEW bow it’s the OLD bow. Using the OLD ammo, is a self defeating cycle.
