well i always used deegie sights, and harpoon is my 2nd one that i like :O ,gonna give it a try if it gonna have that bug i guess ill have to use other sights.thanks for help!!!
i don't know if its a bug or some mods feature but i don't like it.
the issue is when playing i click twice ammo button (eg.2 or 3) the ammo doesn't change immediately it only gets used the next shot.
what mod is causing this,i only use your modpack.
