The original in-game attribute UNSTABLE MOLECULES interfered with the 'branding' system used by Freedom Force X to identify custom characters.
To solve this, Ive removed it from the attributes list and replaced it with an identical attribute that works via scripting - same name in game, same cost, same effects. Any characters who are scanned by the FFX Control Centre will automatically have this attribute replaced without you even noticing, and everything will work exactly as before.
Be aware, however, that this attribute will not work for those characters if you take them into a non-FFX game.
