Collaborative Event - Witch’s Castle now missing

So there was an announcement about the Witch’s Castle and an event. I occasionally will play some levels of Witch’s Castle and so I did the update. Well the update was let’s say a bit bad and Witch’s Castle was broken for just over a day.

They have released a fix but now I have noticed the announcement regarding the collab is missing from the CRK announcements. Does anyone know what might be happening? I have poked around the social media platforms but can not find anything. Just interested if it will appear again, the launch was originally the 10th, then the announcement changed to the 13th and now it is gone.
