level 5 auxilliary can be converted to level 5 urban barrack when level 4 barrack without the proper technology for level 4 barrack

Very good catch, I need to put a tech requirement on the urban barracks.

i'm not sure if it's okay to post it here, but i wanted to ask something about unist & buildings pack. buildings doesn't appear in campaign map. is it just me or graphic is broken?

Just wanted to chime in that I'm incredibly impressed with the building - everything from the historical accuracy to the tooltips to the perks. Very good job.

Please re-add the t4 training sites that were removed with patch 15

It could help to have a tech tree for all the buildings, like the religious ones for example. With stats, I mean..
