AA guns not firing straight???

[Systemlord]

I can't seem to get my AA guns firing straight, every time I fire my AA guns the bullets shoot off to the side rather than directly at the bulls eye. I originally had SH4 which I might add had little to no bugs and now the gold edition, the U-boat Missions seem to carry over all of the bugs from the previous game. Also my crew no longer asks to man the AA guns (Engage/Maintain Orders/Dive to Periscope depth) when an air craft is spotted, just like it did in SH3! I remember in SH3 that rebooting the computer fixed the AA guns from shooting off to the sides. It doesn't seem to fix it anymore, how sad!
