Halloween event on console

Just updated the game, I see the event tab with the challenges on the big book where Okri's challenges are and all that, but I don't see any change at all in the maps nor the keep. Tried a run on Halescourge and couldn't found anything about the supposed ritual to interrupt (despite guides claiming it's near impossible to miss). Am I doing something wrong or does the event start later on console? Just to make sure!
