[Silver_Silence]

I was hunting a large merchant ship off Casablanca. I hit it with one torpedo and follow it submerged, tracking it with hydrophone, waiting for it to sink. The whole time the ship is more or less ahead of me until my sonarman lost track of it. I thought it simply come to my hydrophone's blindspot at 0 degree. I take a look with my periscope and couldn't see the merchant vessel. I realize that I come to Casablanca! This must be its intended destination. After searching the port though, I can't find my ship.

Does it simply disappear after it reaches port? I was hoping it would come to a stop instead.
