i am in a non-dedicated server with my friend and i and the grappling hook (from this mod, reusable grappling hook) works for my friend, everytime she fires it consumes it and than it adds one back in to her inventory but no matter how many times i make it or how many different crossbows i use it wont work. i even tried using my friends grappling hook and crossbow and it still doesn't work, it just consumes the reusable grappling hook and doesn't give one back. than i detach and i try to fire again and it says "no ammo"
