Hi, I’m trying to fully restrict the Impact weapon proficiency on an IW5 Plutonium dedicated server. The goal is to make any custom class using Impact become locked and unselectable in Choose Class, exactly like a class containing Final Stand when that perk is restricted by DSR. I confirmed the correct internal name is specialty_bulletpenetration, and the stock IW5 UI explicitly checks getmatchrulesdata("commonOption", "perkRestricted", "specialty_bulletpenetration"). I tested gameOpt commonOption.perkRestricted.specialty_bulletpenetration "1", but Impact still remains usable. I also tested another weapon proficiency with gameOpt commonOption.perkRestricted.specialty_moredamage "1", and that also did not lock the class. Regular perk and deathstreak restrictions such as Final Stand work correctly, so this seems specific to weapon proficiencies. Does anyone know if weapon proficiencies use a different match-rule field than commonOption.perkRestricted, or if proficiency restrictions simply aren’t implemented on Plutonium IW5? I’ve already tested ClassReplace, but I’m specifically looking for the native class padlock behavior, not a post-spawn loadout replacement.
