I've just finished patrol and I've noticed strange thing.
I was hardly attacked by escort long time with many hits. After some hours being submerged I've decided to emerge. When my uboat emerged I heard and read that my watch crew are down. I don't know reason of it, because there were no enemy ships or planes near my uboat. All my watch crew (1 officer, 1 petty oficer and 3 sailors) at crew manager screen were in red color (I've made them funeral by right mouse button). After returning to port in debrefing I've read that no one from my crew has dead during patrol :hmm: .
What happened?
