Well jeez, here's the problem:
All 4 of the task forces in the eastasiacampaign.mis layer Start with a full compliment of destroyers. Every destroyer in each task force is of the same type. So, for example, BBConvoy2 has 9 Akizuki-class escorts. Same is true for the convoys. For example, Convoy1 (which I believe is the group I encountered, and yes, I overcounted the destroyers
) has 8 small passenger carriers escorted by 7 Akizukis and 3 Agano CLs (it should also be noted that there are, mysteriously, 13 Aganos total present around the map December 41 to early January 42.
Looks like this was rather rushed, perhaps with simple copy and paste jobs that were never fleshed out or made appropiate for the campaign.
