There have been a few crashes at start, but not for a while.
Infantry seems more resistant than in PITF, which is a good thing. The bad things (from the allies point of view) are the Tigers and Panthers.
I have just finished a combat where I started the game with 9 Shermans, including two Fireflies, camouflaged behind hedges around the path of access for two german Tigers. It seemed ideal.
But the Tigers had no problem spotting them and destroying them. (what exactly does "camouflage" mean in this game?)
More problematic: one Tiger was shooting at me and remained invisible while doing so from open terrain behind a treeline! Given the size of this beast, it seemed to me a bit awkward.

I called air support but the Typhoon that arrived merely strafed the Tiger, only killing infantry nearby.

Another fight against Tigers and Panthers on another map had the same outcome: the german tankers are more accurate in their shots and when the 17 pdr guns touch their targets (1 time out of 5 it seems), their shells do not go through.
And you ? Have you been more successful against the german menagerie?
If the germans are that tough, we are going to need strategic bombing to get through.
