Okay, today is halloween, but I still can't start this quest. Is it because there has to be an event? And if so, when does it usually start?
You can get Smores from Nightmare, Rotting Skeleton, and Scarecrows all year round https://royals.wiki/use/buff-potion/2022244 There's actually a room you can farm Nightmare and get Maple Pop's too, they crashed with the goby nerf, but can be a decent farming spot. I use them as a makeshift Speed Pot personally.
To clear a few things up, sometimes our events come a little bit later depending on admin/staff availability. There have been no official announcements regarding upcoming events (including Halloween) for this year.
Can someone else check whether Olivia's quest is available? I can't update as there's an issue with the downloads' page on my side. [UPDATE] I have installed the new setup and finally activated Olivia's quest.
