We ran into several issues the first of which was Port attack. I described what occurred in the other thread that was started by Lingering Frey who looks like they had pretty close to the same problem.
1a. Port Attack - Just as a recap from that other thread, the first port attack was done on a ship unit by a nav air unit during a surprise attack with no ground or other unit present in the hex. The unit was destroyed but remained on Bill's screen but was removed from mine. His destroyed list did not show it present while on mine it did. The same auto savegame did not have matching numbers between our 2 computers. Redoing an earlier save and placing a ground unit in that target hex seemed to allow the attack to go through ok.
1b. Port attack - This was a surprise air attack onto a port with all types of ships, an air unit, and a ground unit present. This was done by 2 British air units. The game locked up with no crash pop-up occurring. See screenshot here again.
