I do not know if anyone has had or noticed this problem but it has to do with the compass reading and the periscope reading.
I set my heading to 180 and was on that course for a couple of minutes, I was attacking a destroyer that was trying to sink my boat, I slowed my sub to 1/3 speed come to periscope depth for the attack, I had waited for the destroyer to get in front of me for a straight on shot at midships, I used the external camera to make sure the destroyer was running across my bow, went to periscope view to make my shot, destroyer was in periscope view at 180 degrees then I notice my compass was showing my heading as 330 degrees, I made my shot, 2 torpedos from the bow went to external camera view to check torpedo wakes, both torpedos left wakes from the bow and straight at the destroyers port side.
Has anyone else had this problem?
