I was on Titanic Tuesday last night, also.
A squad mate was several sectors to the south of my position, but when he keyed his mic on squad channel, he appeared in my sector on the clipboard map. When he wasnt keying his mic, the phantom orange dot persisted in the north, incorrect sector. He landed in the south, re-launched, yet the offset phantom image returned.
Is it possible that you had a phantom image somewhere near enough to get hit by a ship gun? Even if such a bug would not be visible, you may have been unlucky.
A stretch, I know, but may be the two phenomena are related.
