- Crynsos made a modding platfrom, where every faction leader is unique and every region is also unique.
- This mod is using that modding platform and requires it, at least in campaign
- If you are using for example Lokerian's Modular Factions this mod won't work
- There is usually vanilla edition for my mods also, so use that instead, if for some mystical reason, you don't like unlocker made by Crynsos.
