I can’t get the sidearm barrier champ mod - don’t have video evidence but when I try to ‘purchase’ the mod from the Nightmare Harvester, it behaves as if I have successfully activated it as long as I am in the artifact menu but as soon as I exit and return to the artifact menu, it is as if I haven’t chosen it. It does not appear in my arm mods submenu either. Just keeps resetting. I have quit the game and logged back on between sessions of play and have reset my artifact twice.
