Please, I am playing the world cup.
I havent never played Nomads Invasion before.. I have gotten the level 7 fortress in the capital (province 1).
I ordered the upgrade of fortress level of the province4 and the fortress level of my province 1 downgraded for level 6. Is it ok?
I think it is a bug ... but I am not sure, since I was attacked and the fort was not destroyed...
