Here are my notes from playing through Germany East 41-42 with an imported core on standard difficulty. Most scenarios were tough but balanced.
Novgorod - In this scenario I learned during deployment, NOT to place a unit on an exit hex.
Leningrad - In my first couple attempts at this scenario I couldn't get some of the secondary objs to complete even though I placed the artillery in the correct locations. I think it happened when Soviet units temporarily reoccupied the hexes after my first arrival in those locations. Afterwards, looking at the scenario in the editor I saw a bunch of other objectives that never showed up in any of my plays, I would never have been able to compete them anyway as it always took all the turns just to place the artillery.
Streets of Moscow - With Female Factory Labour the Germans were short of supply to deploy all their Land CP's. The airfield north of Odintsovo doesn't appear to provide any supply so the Germans start with negative air supply.
Vitebsk - All trains were in the correct locations in the south of the map but no achievement given for the secondary obj.
Kharkov, Simferopol and Sevestopol Assault- Insufficient supply to deploy all CP's.
Novoanninsky - Insufficient supply to deploy all CP's. Ended early with one Primary obj still to capture.
Ilovlya - Problem already mentioned.
Storming Stalingrad - Russian Air doesn't move, not even to land once they are out of fuel. I'll count that as a blessing as I was too busy trying to deal with all the Russian ground units. In the end, I could only capture three of the six objectives but got the Major anyway because we already start with three.
Stalingrad Docks - Ended 8 turns early after capturing the fifth objective, since we start with four.
Kotelnikovo - Ends as soon as you have the primary objectives, so no chance to evacuate 12 units.
All in all, another great campaign. Thanks!
