Weird. This hasn't happened when I was testing out the game for release. For now I would recommend restarting, but I will try to fix this whenever possible! Would you mind telling me more details?
In the initial run, did you talk to Luna after defeating Fjora? If you didn't the following quest would not have been given.
I don't really know where it is on mac, but there should be a console log for the game in the AppData directory. If you could send that I may be able to figure out what happened
Anyways glad you could pass this quest in the new run! Hope you enjoyed the update!
