For some reason they're all being shuffled. I made Serbian knights and hussars recruitable in Serbia but they're only working in Croatia, where the Croat axemen, and I'm for some reason able to recruit Hussites in Milan where the Condotierres should be, rather than Bohemia.

Any suggestions as to why this is happening? I've checked that I put the right hidden resources in the right places several times.

If someone knows how I can fix this I'll upload an add-on for Expanded Americas, although with more AOR regions.
