@Zach667711 Finally got around to testing this using PermissionsBukkit, and realized you got the node wrong. It's "commandDisable", not "disableCommand". Sure enough, when I tested it with the correct node it worked perfectly. Use War Zones with the "warZoneFriendlyFire" option set, or if it's a separate world you can add that world to "worldsIgnorePvP". That message is given when the specified faction is not normal, i.e. wilderness/no_faction, safe zone, or war zone. You haven't manually modified factions.json and changed faction IDs around, have you? If not, what is the faction tag of the faction in question? After skimming through the related code, another possibility: do you have a player who has been on the server whose name is similar to faction's tag (i.e. faction tag "dead" and player name "deadly_archer")? A lot of code depends on the player's actual name which is stored in the FPlayer data, and the chat name handling is currently tied into that. To change it so that it uses their display name would take careful recoding to keep from adding more processing overhead (thus potential lag).
