A Couple Of Issues

[Folducker]

I guess it's possible to be spotted from the air, bombed and sunk even thou you are at periscope depth? I sunk 37,000 tons using all torpedoes and was waiting for the destination indicator on the map to turn gray so I could go home. Cruising around during daylight hours, at periscope depth on high time compression, lots of planes coming and going, next thing I know I am sunk???

When you hit a ship with two or three torp’s and it goes dead in the water but doesn't sink. Do you have to hang around and either put another fish in it or surface and take it out with the deck gun to get credit?

What means it when you give an order, and you get an "unable to comply?" message. I had a convoy all lined up and nothing. Looked like the crew was taking a nap.

I read somewhere that there is an indicator that tells you how much noise your boat is making but I can't seem to find it. Is it a mod?

So far I am really enjoying playing, want to get through my first career before I start adding realism or mods.
Thanks
