After six turns the Japanese AI air activity pattern is clear:
1) attack Mount Gough every turn
2) no attacks on coastal batteries
3) attack Kai Sak airfield every turn, even after the CW air force is destroyed
4) attack Shing Mun Redoubt every turn
5) No attack with more than 2 air units
Yes, I believe that the information that gives the Air units their interest is not getting "refreshed" as it should...will work on this a bit
