so I remember during my last game that it was a lot of fun when Magyars invaded Pannonia and literally looted the hell out of everybody around me, leaving me in such a position of relative strenght...but in my current game I'm in year 907, the old man Arpad already died aged 60 and his sons just seem to be chilling in their original lands (they split'em up amongst 2 of his sons). They basically spent 40 years fighting pointless rivalry wars against other nomads and stuff, so the question is: what makes them click on the "cross the carpathians" option ? it is only available for a limited period of time, or only when Arpad is alive? Why aren't them coming to the party in the west?
