Sudden Death

[DC2Sal]

I not sure which mod is responsible for this. I am only using NYGM 2.0 and the latest SHIII commander. It is summer of 42, after I attack a convoy the destroyers close in on me, they will lay down a carpet of dc's and after a while I will get hit, only minor damage up foward , nothing serious, at a depth of 160m the damage control team responds and I start to bring the boat up to a new depth of 100m, meanwhile the lights keep flickering on/off. Then just when I think the damage control team has everything under control all hell breaks loose. Men down on deck, 3 compartments are flooding now. I'm at a depth of 90m there was no other series of dc's it just all of a sudden happened. Then I lose the boat. Destroyed by pressure. This never happened before, does anyone know why this is?
