@Marco:
IID in Baltic (end 1940) has the same turm as your picture. It's the IID 1 (without wintergarden). Later on, you'll have the IID 2 (with wintergarden)
Before leaving bunker, i have chosen the twin Flak, and the AA view is ok according to the choice
Maybe you have a mod soup, or it's because you are not up to date...
