Hello. I have a rather odd question/request. Does anyone know if there is a mod that allows me to make monsters ignore selected players on the server? (ignore as in: they exist but simply don't attack that player). A command akin of /monsterignore <player_name> I tried looking through internet to find such a mod but cannot find it. I don't know if such command exists either. EDIT: Monsters = as in Bowtorn, Shiver Drifter Locust Bell, Those specific ones
