I haven't been able to read much on this forum, so I apologize if I repeat anything already brought up. I been playing .11 version...
-my troops are in an allies country, when retaking an allies province, it gives it to me instead, and says that I occupy my own allies province, and I am unable to give it back to them through deals.
-reserves when upgrading have the tendency to upgrade to the latest version, ie 41' reserves, and then keep upgrading, reverting it back to 35' division, sometimes in an endless loop. The same has occurred with marines, but only when it came to upgrading to 45' divisions. I think it may have something to do with mech marines, cause some marines upgraded to regular, and some upgraded to mech, only to be re-upgraded to 35'.
-Aircraft when on missions dont seem to upgrade, I have to stop their missions for them to show up in the upgrade slider. This would make sense, but seems different from the norm of everything else upgrading regardless of its location or mission.
-transports, no one has enough of them, germany has few for Norway and they dont use them, and no one seems to build any, but thats an ai issue. However with the different transport models, it seems that model 2, is cheaper, and takes hundreds days less to build then later researched models, even though the model 2 is superior in almost every way except for speed. There is no incentive to research later tranport techs.
-japan has a semi-industrialized economy, is it still possible to research heavy industry with a semi-indy? If not it will prove a big handicap for japan as they will not get any ship building bonus' nor any oil conversion which will kill their war effort. Perhaps an event can introduce a full-indy?
-there is not much difference in speed when it comes to attachments, shouldnt artillery slow down a unit, and shouldn't mech recons speed it up?
-naval bombers, seem great until late war model which increases the attack from 6 to 15? This is a bit of a dramatic increase from the 4-6 increase.
All in all, its a great mod with a lot of potential, once some ai is incorporated to match all the excellent additions you have given us.
