It`s happened with me too! I played with greeks, and i get a scandinavian province, [Hyperboria/Themiskyra]with greek garrison inside far far away! This province had a greek temple... Few turns later the settlement was besieged and lost.
But... suprise... it revolted and i got it back... and lost, and got back...
After all destroy temple.
Strange story.
Maybe it is a reason why gauls get GALATIA [they are only in Pannonia in my campaign] or the the Sarmateans take Euboea [near Athens] but maybe this is a naval invasion... it`s strange but i like it...
