Okay up to this point.

ERROR! ERROR! ERROR! Danger Will Robinson!

Let's say that happens at bearing 012. For my torpedoes to hit the ship, at 90°, I have to fire the torps when the ship crosses my crosshair at bearing 012.

See, your AoB is wrong. Your AoB for the TDC is AoB at the shoot point, NOT AoB at the impact point. In this case your AoB is 90-12=78º Port. Your AoB is 12º off and your torpedoes are going wrong just as you told them to.

In other words, basically the torps should follow the black line on the attack map, which is not happening and they are deviating.

Not if you tell them not to do that!

It looks like the TDC is just keeping the first gyro setting at bearing 000 (which would be 34#is), and it is not adjusting after sending again the "range" and new bearing at 012, although it is marked on the TDC dials

And now you know the torpedoes went EXACTLY where you told them to. Before or after the save is a red herring, a distraction having nothing to do with your targeting problem. Your procedure is wrong.
