Was your pressure hull damaged? AFAIK if thats gone you shouldnt even dive at all because the pressure finds the weak spot and crushes you like a coke can
.
I noticed one thing don't know if its been done before I had just sunk a flat top...starting to dive to about 50m and all of a sudden my battery goes flat, loose all my fuel, air runs out and my sub seems to fall apart lol, there wasn't a single DC dropped either was completely random I was a like "Huh?! WTF!?"
