I'm trying to fix the Prototype Durantium Driver, as it has an error that makes it cost 12 (!?) Durantium and 1 Thulium, but... I can't find where that's supposed to be fixed? It's been a *long* while since I tried modding stuff in GC3. Do I have the right file? This is in SteamApps\common\Galactic Civilizations III\data\Game\ShipComponentDefs.xml
