Is this water around my feet?

[Walruss]

Ok, so I wandered a little clsoe to the boat as it exploded, I get that. My bad.
I take some dmage and some crewmen are injured. Watch officer took a pieece of shrapnel to the head and died instantly Hydrophone reciever torn clean off. Shockwaves from an underwater demolition causes some damage below, and the petty officer in the electrics room falls and knocks his head. I also have some minor flooding in the bow quarters. I can live with that, it's not serious and the damage control team can fix it. I decide to head home for repairs and hospital for my injured men...
4 days later- 4 DAYS! I get 'we have heavy flooding sir'. The leak still isn't fixed. The bow quarters (and there only, torpedo room is fine) is now 3.4 full. Boat still floats on the water, but I change course to a neutral norweigen whaling station just in case. Halfway there (and anout 36 hours later), i get 'ship destroyed by flooding' - we didn't SINK Oh no. The bow quaters just filled up.


How The Hell did this happen? A leak that takes 5 and a half DAYS to flood should be fixed by damage control, no? Or are my whole CREW scared of water? Fatigue modelling is offf, so that can't be the issue. And how does the ship sink from flooding if it DOESN'T sink!

Is there a mod that fixes this? I had a career end of similar issues a few weeks ago - depth charge caused it and it took 2 days to flood and 'sink' us (still being on the surface' but otherwise same issue.

Halp?
