Yeah, send a note. Linked questions used to work (before we had so many lovely tournaments), but they don't really any more. Usually the link can be fixed with a relatively quick rewrite, and then the next time the cache is updated, the question will work much better in the tournaments.
If you're worried about the player's reaction (if they're still on the site), I've seen some very polite notes saying things like: the question was good/interesting, but it was confusing to see that first sentence in a tournament where the "question above" was totally unrelated, etc.
