Random sink?
 

Hey guys,

I've got this strange thing which happened a few times already.
This time I was cruising on periscope depth with 180m under the keel. I was following my torpedo's how they would hit a ship when suddenly my hull gets damaged, as well as the periscope and battery. The next moment I lay on the bottom of the ocean :-? Which all happened in a minute without time compression.

I'm sure there was enough meters left under the keel. Does anyone know what I'm do wrong, or not see?

Perhaps you were attacked by either surface or aircraft. Was the merchant armed?

Nope, none of that. I immediately checked the surrounding with the external camera. There were no aircrafts or ships in the perimeter, I'm really confused.

Thanks for the quick response though
