I have a WWI scenario and I'm trying to set up an event where if Hungary becomes independent, Austria-Hungary dissolves via forming into Austria. I've tried several attempts but it seems either it doesn't work, or it does it when Hungary isn't even controlling territories (but they are an unreleased vassal of Austria-Hungary, via cores). Is there a way I could fix this?
Like if I do "Trigger: Civilization: Hungary Exists" and "Outcome: Form Civilization: Austria-Hungary -> Austria", it does it even when Hungary's not on the map.
