Is there a known bug where a ship doesn't register on the hydrophone? I had a merchant about 2000 yards off my starboard - and all the time I couldn't get a hydrophone reading off of it. By pressing the right buttons I could get my operator to call out the contact bearings, but yet I still couldn't get a sound out of it.
I was at about periscope depth in rough seas - if that at all matters.
Running 1.5 with the latest TMO.
