Some random bugs

This is the right place for bugs, yes?

-the Citadel, which is supposed to unlock Paladins, didn't. I thought maybe I was missing a hidden requirement, but no paladins after having crystal, horses, metal, and free logistics. Is there another requirement not listed by the UI?

-Equipped a healing ring, but the ability shows up with a red cross-out, and can't be used.

-You can equip items on the warg unit you start with, but they don't seem to adjust his stats.
