My dwellers are not able to use my Burnmaster for any sort of self-defense, whether they are fighting radroaches or raiders. Whoever is equipped with the weapon does nothing more than run around helplessly. However, other weapons work fine. I have tried equipping various dwellers with the weapon, restarting the game, equipping it during conflict, and some other things, but I have not been able to make it work. Is this a known issue? I received the weapon in a lunchbox that I had purchased out-of-pocket, so I would really like to be able to use it. Thanks.
