My two armies, one Hector and the other Hero got stuck at the same spot after trying to invade the city of Methymna (up). They went around the island to land onto the friendly shore where Paris captured Eressos a turn earlier. They landed there and froze. I have military access with Paris and tried switching different army stances, but I simply can't click anywhere so they can move (the movement range indicator doesn't even show up).
How do I fix this?
