No depthcharges...

Hi again...

I´m out doing career in my S-sub again in the mid of 1942. On a mission, photoing Jap. carriers, I couldn´t refuse to put 4 fishes in one of them. Heading out to deeper water at flank speed I was caught up by at least three pinging destroyers. However, they seemed to loose track of me very easy. I was passing one of this thermal layer on my way down. All of a sudden they stopped chasing me, no depthcharges was dropped. They also went over the sub in shallow waters, me at periscopdepth. No depthcharges there either. Is something wrong here???

Me using RFB, and very hard settings in the career.
