I'm playing as the allies on default difficulty settings and I suspect that the game cheats. Some examples are:
* Japanese infantry doing amphibious assaults then attacking twice.
* Units disappearing from Taipei and then reappearing on the Chinese mainland - I've tried doing operational movement from there and the game won't allow it for me.
* German economy showing saved MPP of 890 in mid-41 despite having a mega army deployed on USSR borders and also doing well on the research front (+2 subs and aircraft).
I don't mind if it cheats for play balance as long as I know it's happening. Unfortunately the Axis AI turn moves so fast that it's difficult to see all of these things in detail and find a smoking gun.
