I changed the load order, activated the tycho patch last and patched the .exe that had been previously patched with h.sies pach. It didn't help.

The bug does not occur in the naval academy torpedo mission. But in my campaign, I just intercepted another single merchant, got a perfect hit...and again, the map contact disappeared and the ship vanished as described in the first post. I'm getting kinda desperate here.
