Rogue or Druid vs Night Elf Hunter.
Hunter casts Flare, rogue can see it at her feet.
Hunter shadowmelds, and the flare disappears. Bur rogue steps into the flare radius... it's still there and active, you just can't see it.
And interestingly: even if the hunter moves, breaking shadowmeld, and completely leaves the area of the flare, that hidden flare is still active, still hidden, and still breaks rogue and druid stealth.
