Great map but I've encountered a few issues.
First, a few of the town/city/village hexes didn't change ownership when one of my units enters it. Notices in Iceland and Turkey.
Second, some units will double or even triple clone. Example, I move a light inf. unit 2 hexes and it still shows in the original hex. Cloned units don't seem to be movable but never disappear and you can't delete them.
Third, sometimes I can move directly onto an enemy unit (ground units on ground units). I can then attack on top of the enemy unit.
Fourth, units can sometime walk on water w/o embarking/debarking.
Finally, all four of these issues are related--that is, they've occurred (for me anyway) on/around the same town/city/village hexes in Iceland and Turkey.
