I support the idea of locked garrisons. I did so for the UK already so it only seems fair that Germany deserves some.
As for the rares, I don't know.
Will release a 0.4 this weekend.
Hey, I played some games with .3, and the tweaks you made to the AI really made it quite good! Germany lasted until 45 for the first time (I was playing as Nationalist China in a normal manner, so Europe was purely AI vs. AI).
The one thing I noticed was that Germany still lets a large number of troops get pocketed around Nice. 10+ divisions. I'm not sure how to fix that but if those were deployed defending Germany then the outcome would be quite realistic. Also the Soviet advance against Manchuria is quite slow. Maybe station some Soviet armored or mobile divisions in the far east (and set the front ratio for the AI so it won't just try to deploy them against Germany). It took the Soviets until late may just to advance through half of Manchuria.
