Taking damage for no reason

[kakemann]

Hi!

I'm trying to understand why my sub sometimes takes damage while attacking convoys or task forces. I've experienced it a couple of times now.

One of my experiences:

I saved a game before attacking a task force. I was lying at all stop,perscopedepth waiting for the fuso battlehip to pass. I had a Porpoise sub. When i got a nice fireangle i fired 4 torpedoes at it, and 2 aft against a nearby destroyer. I hit the battleship 3 times and the destroyer with both torpedoes. went to 40 metres.still all stop.

A nearby destroyer started moving towards me, but was far away. after a minute or so the sub suddenly started to take damage. the destroyer was as i said far away.
I got serios damage and sank to the bottom.

As I said, I saved just before so I loaded the game again. This time I did the exact same thing. But I went to free cam view to see that none of my torpedoes hit me. Right after I hit the ships the exact thing happened again. I suffered damage and sank.

Anyone experienced this?
Is it a possible fix?
Thanks anyway!
