Watch for DD "convoys" by late 1943, that will "grow" to 30+ DD by mid 44. I think its 7 DDs that were probably supposed to be set to DockedShip=true but were missed. If you want to, you can try to edit them in the Jap_HarborTraffic.mis file. If I get a chance to this evening (and if I remember to), I'll run my pre-built search for them, and let you know which ones are problems.
