Thought I was a goner
 

My boat was rocking all over the place after hearing a pretty big bang. Looks like the gunboat managed to blow itself out of the water with a depth charge. This happen a lot?

:rotfl: Gotcha !

Not often but too much
 

Here's what is happening: The depth charges have two settings: one for depth and another for an uncertainty factor, plus or minus, of exactly what depth the charge will explode. Because of hardcoding in the game, if the depth charge is set shallow and the uncertainty factor comes up a large minus, the depth charge can explode almost on contact with the water, giving the ship no time to get away from its own depth charge. KABLOOEY! (blub, blub, blub)

I've never had it happen to me in 14 cruises. Others say they see it constantly. As people enjoy obsessing about "fatal errors" I believe it is pretty infrequent.

I once did an emergency surface right in front of a patrol craft,who then went into reverse and had it's last DC salvo go off right under it's midships. Was rather spectacular,the DCs caused the patrol craft to explode and it broke in half.

I think it probably saved my pixilated life. I only surfaced because my boat was heavily damaged and I figured I'd rather go out with guns blazing than take another close DC pattern.

I suspect the shallow DC error is more likely to happen if your own sub is also reatively shallow. Most of us go deep and the AI knows that.
