I'm sorry to ressurrect this thread but I have a problem as well. Like one person before me I tried adding a Broken Crescent unit into Stainless Steel. I chose Vestiaritai.
I *think* I did everything fine and the unit plays fine in custom battles - the textures are there and so on.
But when I start a campaign, it doesn't launch just takes me back to the menu where I can choose between the campaign and custom battle. What could I have done wrong?
Any help would be appreciated!
