Played till round 54 now on update (part 1 v7). AI now builds def UUs, had fun seing the WW2 units on the battlefield.
But seems to be that that there are to be some fixes on unit's flavors.
Playing as germany I saw LOTS of SU-26 on the russian side, a little bit of KV-1's and aircrafts. On italian side lots of "...letts" (forgot, were artellery an anti tank units, u know with xx/xx behind) and aircrafts. england had lots of ships, aircrafts and I saw one churchill.
For me, going on the battlefield with King Tigers and other endgame units I think that the flavors for the later game units have to be raisen up, exp. for all armored units.
Hope this information helps you to make the mod eaven better, I will report you every time I stop playing. (In my country it's 4:38 am now, so be sure this mod makes lot of fun
)
