Okay, I found out a little more about the problem, or rather what the AI is trying to do.
My AK's are being requisitioned by the Japanese to pick up the 34th Sentai in Osaka. Strangely, a few turns ago a fragment of the 34th Sentai (2 lily's) appeared in Amboina, which I hold as the allies. It seems I can transfer this fragment Sentai to any allied base, but I can't give it back to the Japanese (AI). Unfortuantely, I can't disband or withdraw it either.
The AI, is taking an allied task force to Osaka, to load the other half of this Sentai and send it to who knows where. I have lost about 3 AK's sunk and 4 damaged around Truk due to this bug.
Perhaps I should load it on an AK and send it through Japanese waters to get sunk, thus hopefully ending my problem.
The problem occured while I had patch 1.801, but is still there with 1.804.
