Added this:
"Blacklisted Chat Commands": [ "/tp", "/remove", "/bank", "/shop", "/event", "/rw", "/home", "/trade", "/callheli", "/kit" ],
But after duel is over players can not use /kit. I have to reload plugin to make it work again.
/kit still blocked after duel
this can only happen if the player is queued or in the zoneif (duelsData.Queued.ContainsValue(player.UserIDString) || DuelTerritory(player.transform.position))

give this a try. I changed the message to be specific to why they're blocked. I'm also removing them from queue when they teleport incase I missed it somehow.
