Cool down. It's obvious that the campaign has to have some kind of scripting. It would be nice if a function deleted a sunken ship from the campaign layer. But it doesn't. That's not a bug nor a big mistake. Perhaps a moddder can give us this feature sooner or later. If not, SHIV is still a lot of fun IF you want it to be.
The world isn't perfekt, this game isn't. Chill.
