So I've played through two campaigns past 100 turns now and the only unique units I have been able to find/recruit are the Dangyang Troop, and in their info page it specifically tells me I can only recruit them in Dangyang province. For the other unique units that you don't start with at the beginning however ,this is not the case.

As the Liu Clan I started with the white plumes in an army, however after upgrading multiple settlements to the highest level and having imperial barracks I could not find the 'Unstoppables', or the 'Shock Brigade'. I checked in the building browsers of all major cities I owned including Cheng Du and I cannot find them.

This is the case for ALL unique units, even for Xiliang Cavalry, and Yuan's unique troops (I disbanded the 'Suicide squad' to test, and I could not recruit at my capital, with the highest level barracks possible.)

I wouldn't usually care too much, but being a civil war based mod the few unique units, they really make it that much more playable.

Am I missing something blindingly obvious?
