convot attacks in storms

[Laffertytig]

so the vibe im gettin here is that nygm handles this issue in a more realistic manner than gwx.

a uboat should be the one that detects the dd not the other way around, unless the watch are asleep. my 3 attacks show that either the dd's had radar in oct 41 or they can see through storms. certainly made for a very frustating patrol and all for the wrong reasons
