The Empire - 1.5 bugs?

I apologize if I'm asking this in the wrong place, but I couldn't find a bug thread.

I have a problem playing as The Empire in where I cannot recruit any archers or missile units of any kind even when building the archery range anywhere on the grand campaign map.
I can only use the archers you start out with. I thought maybe I had to trigger some reform, when the scroll popped up asking me if I would like to reform I clicked yes but it hadn't done anything to my military.
Failing that, I don't know how to recruit mercenaries or auxiliary, they dont seem to be available.

I can recruit archers playing with the other factions on grand campaign like Skyrim but I can't as The Empire. I can get missile units in custom battles though so I know The Empire have them.

So how do I get missile units as The Empire on Grand Campaign?
Is the military reform trigger for The Empire broken?
Where on the grand campaign map can I go to get mercenaries with my general or the Elder Scroll 5 looking auxiliaries?
