In the Panzer, selecting HE or smoke rounds when I am in the main gun gives me a messed up view. I can switch back to the AP rounds and get a correct gunsight, but when switching back to HE or smoke, it is messed up again. I get the range lines, but a view at the wall of the tank, and it moves around as I rotate the turret, looking at other walls and parts of the tank.
This is after selecting the first rounds package (60 AP or whatever it is). That package doesn't list that there are any HE or smoke rounds as well as AP rounds, so perhaps the messed up view is just telling me that I don't have any HE or smoke rounds.
