it means when I load it, there's a background popup that shows up (behind the editor in my case, check your task bar) and says random group error. (edit-after rechecking, it's that damn akikaze again)
SM129 error is explained here:

It has to do with a type change, from 1.4 (battleship) to superbattleship in 1.5 I've not tried this fix to see if it works in practice.
Also, another question: Are there general merchants..meaning, merchants that can be jap but are not in the jap roster, IE generics used by all sides? Or are they required to be in the roster of the matching country to be used for that country?
