S**t happens mate... Really bad luck...?!
I stopped playing 1939, start my patrols in 1940/41 as there is no real challenge in "39... if you are not intruder into Liverpool or ScapaFlow
...
I enjoy playing first quarter of 1942, the best gamplay...
Reece, it is not worthy of gameply tweak,... just happens once in 20-30 convoy raids in a first year.
