It's now the begining of August '42, the German '42 Summer offensive is only 3 weeks old. I've retreated the whole of my first defensive line 5 hexes to just in front of the 2nd defensive line, as some Panzer Korps had broken through in places in the South of the first defensive line. End of my order phase.
Now the AI, does it turn. I get back to my order phase. First thing I notice that the German offensive in the South is a diversionary attack, because it appears the Germans have parachuted a Panzer Korp

The Panzer Korp is in a supply of 6, wtf?!?!?!
I've saved the game at this point and a screenshot if anyone wants a look.
