HI,
I'm currently playing the GC as Japan and noticed something strange :
A few turns ago, my infantry units where updated from the 1850/70 model to the newest 1870/1890 one (new picture and slightly better stats ). The unused units available in my force pool were replaced by the latest ones ( so I had 6 available militia corps and still have 6 of the new ones).
However, the units already placed on the map where left unchanged and 6 new ones appeared in the force pool. And I think this is not what is supposed to happen : for example, I had already built 5 guards corps and now I can again build 6 new ones for a total of 11 ! Same thing for my other infantry corps and divisions on the map. In fact, japan OOB was simply suddenly doubled !
I'm pretty sure the new models were intended as replacement for the old ones not addition to the force pool (that's why I can't build 6 old model militia and 6 new ones for a total of 12) .
By the way, I wonder if this is not part of the problem with some AI nations having crazy OOB after some time : In my game, Austria is a monster currently waging and winning two wars at the same time against France and Russia ! (In fact, Austria has been at war since the beginning of the game and crushing all its opponents )!
What do you think?
