Odd contact on TDC Map

[Borgneface]

Salute to All!
There is 2 strange things happening in my game:
I am in the middle of a campaign and here is what is happening.....
1) I cannot figure out what it is! Sor some weeks now when submerge, I have a sound contact permanently there on the TDC map. Does any one have an idea of what it could be and how to get rid of it?
The first time I noticed it....I went to Periscope depth and looked for it without any success....It seems it is just a ghost ???
It is always at the same position!!
Here it is:

2) Even though all the crews are at their station int the Command room,, 3 officer+3 helms crews, Every time I raise one of the periscope I get this message: No officer at helm station!

Thanks for your help

On the TDC it appears that the line extending out to 00:30 is your torpedo tragectory indicator. It is a grey line which shows the path your torpedoed will take if you were to fire it right now and the elapsed time it will take to travel the selected range, in this case 30 seconds (00:30) this is not a sound contact. You'll notice that this indicator will change if you move any of the bearing, /speed, range or AOB dials with the TDC switched to manual or any time the weapons officer forms a solution for you

As for the not enough crew, are you playing with mods? If so please list them

Also, go to the crew management screen and look at the command room. Do the icons of the officers and sailors have a red "!" Mark? If so this means that they have reached maximum fatigue and need to rest before they can go back
On duty. You will have to drag and drop another crew member into the fatigued crew man's position. These crewman will recover faster if placed into the stern or bow quarters if there is a medic in the same compartment

I wonder if you were to disable the two aces crew mods if the error would continue. If the error continues it's not those mods

[Borgneface]

I will try that! I'll let you know the outcoe!
Thanks
