Completed Red campaign without major problems. A few bugs/observations:
Get a Red general definitely not working after a while. This isn't a result of a fixed limit, since I had a number of generals killed.
I got Brusilov due to an event. The text in the message box was something like evt_nam_Renforts_Red_TsaristOfficers_Brusilov.
Mogilev stays at 100% loyalty.
Polish AI seemed pretty conservative, didn't advance until 1921, maybe because I didn't have Kiev. When I took Minsk, there was an automatic armistice. Poles also liked to use their airbases like scouting cavalry, so I picked up several of these without a battle.
White AI appeared pretty passive in general. I took Rostov when the Southern Whites were busy elsewhere and their main force spent the rest of the game watching Stalin from across the Don until I cut off its supply and destroyed it.
