In World versus World, there is some Supply Caravans to defend. Those are Dolyaks transporting supplies for a tower, a keep or Stonemist Castle. When a Supply Caravan is alive on the map, it appears with a Dolyak icon and the color of the team owning it.
It is possible to hide those Dolyaks by using some skills such as Shadow Refuge. I know that, for the team owning the Dolyak, the icon will remain on the map. But do the two other teams are still able to see this icon while the Dolyak is invisible ?
