I've just conquered Pella as Hellas Koinon and was able to produce the available units right away. I have the MAK no1 gov building and that one was damaged and a High level MIl building. Even then I was able to make the torakitai, and the better hoplitiai (Forgot the names).
I thought this was only possible with your own faction gov buildings? Or do the greeks faction have no problem with eachothers factionbuildings?
