Updater version number bug is a minor glitch that we are hoping to get to soon, it doesn`t effect anything though.
With regard to your hometown not saving, we usually recommend to:
-Turn off and Turn On your internet modem/wireless router (unplug it, and plug it back in if it doesn`t have Power button)
-Don`t download or upload any files, videos e.t.c while playing DoF
-Make sure Dawn of Fantasy DoF.exe and or Dawn.exe is allowed by your firewall
If the problem persists, it might be due to unstable internet connection, in that case best advise is to Log Out and log back in ever 30 minutes.
