Wanted to add an update to my issue. First i tried the quest i did the next story quest in line plus some other quests first and this one just didnt spawn the NPC's. This time i went with another character and went straight for the mill as soon as i saved King Casimir, but Bernard and Wyrdess Helele was both still missing. Also have an answer for a ticket from one from the team and described the problem to them, so hopefully it will be fixed some time soon
We are investigating reports that Helene is not appearing in the quest “Turning of the Trees.” The FAQ below has troubleshooting that can help. As this is a known issue, we will be closing the thread going forward.
