I just updates some plugins for the 1.5.2 patch and now my factions broke. It was working just fine before. The chat prefix is now [FACTION] instead of the faction names.
New chat string tag replacements: {faction_relcolor} - replaced by relation color (red for enemy, green for member, white for neutral, etc.) {faction_roleprefix} - replaced by role prefix (** for faction leader, * for faction officer, nothing otherwise) {faction_title} - replaced by faction title if one exists {faction_tag} - replaced by faction tag if the player is in a faction, or nothing if factionless {faction_tagforce} - replaced by faction tag regardless of whether in a faction or not Note that additional formatting can be applied by appending one of the formats listed in "chatSingleFormats". For example, to have the faction tag listed with right padding (extra " " space to right of faction tag if present), you would use the tag {faction_tag_pr}. To have the faction tag left-padded, it would similarly be {faction_tag_pl}.
