Hosed by the TDC!

[Antiacus]

So i'm patrolling up in AN23 near the British sub base. I've got 2 torpedoes left and detect a cargo ship at 23km heading straght for me.

"Perfectioso" I say to myself. (i'm part spanish and playing an exile of the Spanish civil war).

So I plot out his course (about 175) and set up for a 90 degree shot at 1km.

Chuckling to myself at my good fortune i set the TDC to 90 degree AOB and 1km range. I also took the opportunity to set both torps at impact and fast speed.

When he gets up to about 3km i point my bow at him and establish 10kt speed. I'm all set! Easy pickins!

reset my bow to 90 degrees to his course, double check his course, make a tiny adjustment to get back to 1km range and i'm all set.

When he gets to 0 degrees on my scope i unlock, set one loose just a little forward, and one just a tad aft.

I smugly wait for the impact and the adolation of my adoring crew.

Nothing...

Hmmm. I set those to fast right? Yeah, pretty sure.

Nothing.

WTF

Nothing.

I check the TDC map and it shows my aim as being well aft of his position at 90 degrees. Mhuaah?

I check the TDC and the far left guage is set at about 30 degrees left of 0. I'm assuming that's relative bearing from my vessel to his. Not sure why this was at 300 but i blame the weps officer.

I tell the crew that we had a faulty torpedo and set sail for Kiel.

I'm assuming that the automatic updating the TDC does after being closed caused this to happen. I'm displeased and take it out on the crew. Port and Starboard duty, no holiday underway, I want no rust showing by the time we reach Kiel.
