Hello to SUBSIM Radio Room!
Have never seen any topic disscusing this problem (Or maybe it only happens to me). So I decided to open a new thread.
First of all I want to say that Im not talking about any mods, because It doesnt matter if you have mods or vanilla.
It's a bug of the main game SH3 with the engine sound. (at surface)
I experience this bug when I play a while with speed, time compression or checking the map.
Situations:
I) I go at constant speed and then pause the game, when I unpause it, there is no sound of engine anymore. (If I change the speed, the sound comes back)
II) When I stay still and do not move, If I pause the game or check the map, the engine sound starts playing... (If I start moving and stop again, then the sound goes off as it should)
Those bugs are really confusing and anoying sometimes, I have experienced it with vanila game and also modded LSH3.
I have played some with the "Submarine_diesel_exterior" and "underwater" but a change of a sound itself doesn't solve the problem.
So is there anyone who knows this bug and how to fix it?
Thanks for the attention and sorry if I have some mistakes with english.

And thanks for the mods

They are great!
