Not 100% sure - hours have passed!
I wanted to start the dungeon Witchwater as a NM dungeon today.
So I looked for it on the map of Hawezar - in the position I remembered from yesterday.
Bugged:
I could not find it.
I believe in the position south of “Serpent’s Lair” (another dungeon) was a dungeon with “Estate” in the name. (Active Whisper task)
I gave up.
Not bugged:
After my session with friends today I checked again.
This time I could find Witchwater first try. (Not a task from the tree of whisper.)
