In this Quest you are asked to light 3 camp fires in order to appease the fire elementals in the Black Shroud. The quest NPC marks 3 spots on your map where the fires need to be lit. Only one is marked at a time, and you don't have to light the one marked for it to count.

So I'm not sure if that is a bug or not, yes?

Also, it's quite annoying how far away they are from each other. If they must be, then mark all three at the same time so I can plan a route to each one and work my way there while doing other things.
