I don’t think this is a theater issue but a Falcon issue.
It’s weird though that two theaters (Ikaros / Aegean) should display different behaviour: in Ikaros, ground units won’t move at all from the north of the island to capture Karpathos in the south, while in Aegean, they do move but through the ocean occasionally. I’m just wondering what the issue is there and wether it could be fixed at some point.
All the best,
Uwe
