Hello, i thought this was Mac-specific but it appears to be the same when playing on Win too. Many times specially playing on earth 1942 scenario the game crashes while doing AI players turn. Often last rows in LUA log is "adding x2 ocean movement points" to some unit, if that unit has a specific name and you remove it using IGE the turn completes successfully. so i think there might be something in embarking that causes the problem because every time those units are located on land before that player's turn.
