Glow Mushrooms in Coastland where old waystone used to be still there.

In the coastal swamp, where the waystone was before it was moved, there are still glow mushrooms. They were likely not removed when the waystone was removed.

I observed and heard glow mushrooms without any waystone nearby, making them obsolete.

Since glow mushrooms are only found and used as a quest item to take away the cooldown from waystones, I would imagine that these mushrooms wouldn't be at this location on the map.
