yup
this was with GWX but without the olc and longer repair times
the most suprising things were 407 meters and still alive, and getting back up and THEN death from pressure (game said i died from pressure)
i thought i knew how the damage model worked but now i'm not sure anymore
i remember a game where i could see the integrity and it was at around 65% after an air attack, i then dived to see how deep i could still go and at 180 meters i started to get damage warnings, blew immediately but integrity went to 64 and my crush depth was thus less, which meant my new safe depth was no longer safe,
i ended up at 60% integrity and a safe depth of 100 meters
i can only assume that in my adventure the hull integrity was already so low that i was being crushed inevitably even though we were on our way back up.
still, 407 meters was a new one for me
