Yeah I found that out mate, changed setting while at sea. Also found that if you click on refit, you cant end patrol.
Gee this game is a constant learning curve
BTW, last night I really got in to a convoy near Edinburgh.
Sank 3 from memory, and had another 6 dead in the water and burning.
Any way the escorts got on to me and gave me a bollocking, and I think what really saved me was the shallow depth I could see the DC's going right to the sea bed and exploding there.
I had flooding, but only in the control room, water was nearly knee deep, but there was no flooding anywhere else in the boat.
Is this normal or maybe a bug ?
