Engine Bug
 

Has anyone else ever had an issue whereby engines are on and screws are turning but speed is zero and sub wont move?

Were you shutting down single engines?

If you ordered the Bosun to send the men to the bunk to save oxygen, you won't be able to move at all. And if you use the external transfer ability.

Nope was neither of those. Literally just loaded a save game and engines are set to standard but no knot speed. Have had this happen before

I had this issue/bug also sometimes in past. In my case two things helped:

1. Just wait for 10 until 20 minutes with timespeed of x125 and my sub moved again
2. Reload just an old save before the sub freezd. It was in my case important not to save the game in this freezed situation.

But I cannot reproduced this to find a possible reason for this issue/bug.

Thanks mate will give it a try

I often have the opposite problem where the sub is stuck at 15kn even if I set all stop. Saving and reloading solves the problem.

Only problem I at times have is that when surfacing the sub will all of a sudden speed up to Große fahrt without me ever having given the order.
