Hey guys,
I have discovered a flaw with Silent Hunter IV. The flaw is that the Anti-Aircraft gun barrel goes through the conning tower like a ghost through a wall

while not being impeded by physical matter, that would normally impede or stop the AA gun from rotating. The Conning tower does not physically stop the anti-aircraft gun barrel, instead the barrel goes through the conning tower like it wasn't even there.
Video proof. For best results, view in full screen with HD. I know, it's dark, I was out on night ops at the time.
Is there any way to correct this? It would be nice.
