Hello, Blueduck!
LSHIIIv5.1 is an excellent mod! Thank you very much!

I play at 100% realism.
The situation:
The beginning of the campaign. The noise of the sea on the tower. Clock ticking on the navigator table. Gurgling of water in the hydrophone. All right!
The game is temporarily stopped (pause) - I need to withdraw...
I continue to play ... The noise of the sea on the bridge.

The noise of the sea at a navigator table.

The noise of the sea surface in hydrophone.

The noise of the sea (rain or wind) at a depth of 50 meters.

!!!
This situation persists until the return to port (or exit) ...
Are You can help whith this trouble?
Best regards, Lance.
