Survivors are marked on map but when I get there, there are no survivors.

Ghosting on map somehow?

I am playing with no mods.

not sure on the survivors thing, but the "phantom" convoy thing is real, and very frustrating.

i "think" that the phantom convoy thing happens at the second spawn.
it's complex to explain, just know that it is not your installation, all of us experience what you have experienced, and there is nothing that can be done to resolve the issue.

just go and find some more ships to sink.
