I'm playing as the Huns, and I can't build any buildings.
I tried the other Huns mod that lets you settle and build in settlements made specifically for the huns...but that too doesn't let me build. But in mod manager (just the one that comes with the game, that is only one I can find available) it says its out of date. So could that be it?
I take a settlement, right click the building and see buildings lit up...but if I left/right click them nothing happens.
I can't play if I can't build as Huns

I know I can be a hoard, but I'd rather make an empire and stuff.
