The ongoing effect of the rumor "World Torn Asunder" says, "each time monsters with the moon dimensional symbol move, place a Clue token on this card." Does this mean every time the moon dimensional symbol appears on a mythos card? Or does it mean a moon monster that is on the board actually moves.

The moon dimensional symbol is shown on the card. But yeah, sloppy wording again

Gah! I assumed that the "Moon" dimensional symbol meant the crescent , not the circle . I assumed too much it seems

No, you are right. Moon does mean the crescent, not the circle.

we've always played it like that if there is no monster with the crescent symbol, it (doesn't exist and thus) cannot move, therefore we don't add the clue token. but if the crescent symbol is shown and there is 1+ monster that has that symbol, we'll add one (1) clue token, even if there are more than one monsters.

(thus, the rumor could partly be prevented by keeping the monsters off board.. unless e.g. a gate opens and the monsters that jump out has the symbol and is supposed to move.)

@ Taurmindo: for Strange sightinings and Dark druid in play, do you add two clues then? Since Crescent can move twice in the same turn, in this way

The rule should be analogous with Rifts and the Dark Druid, which trigger on the presence of the correct movement symbol. So, no moon monsters should be necessarily present.

So, in summary is this correct?

World Torn Asunder: Ongoing Effect

Whenever a Mythos card is turned that has a crescent moon dimensional symbol listed under Monster Movement, then a clue token is placed on the Rumor.

It doesn't matter if there are no crescent moon monsters in play or not, a clue token is still placed.

Even if there are more than one crescent moon monsters in play or if a single crescent moon monster moves more than once, a single clue token is placed.

That is what I would do, yes.
