I've been playing a couple of turns in this campaign, and getting slam-dunked by a very aggressive Red Army and insane amount of arty. I was afraid it would crash because of the latest patches but so far so good.
The AI in the latest patches seems really good and the passiveness is gone it seems, so that just adds to the challenge of this campaign. It's actually fun to get rolled over by the AI for once instead of a turkey shoot.
Question; did you give the Red Army a lot more artillery and spotters? They seem to have an huge amount of the stuff, and able to slaughter my troops just by barrages. It's realistic of course, but I wonder if this is changes in the latest versions of the game or something in the campaign.
I did not really mess with arty spotters. It should be pretty much default. But there where a ton and a half of them assigned in the pool of campaign.
