Skate-o-Ween Challenges don't show on the map

This event has been completely bugged for me and I have not been able to complete any of the challenges because they do not appear on my map. I didnt have any of last weeks challenges available, and figured with this week's update it would update them onto my map. Low and behold not only did they not update, I can't do any of this weeks challenges either because theyre not availble. I have no challenges with ghost icons anywhere on my map. No point in partaking in the event if I cant even get the rewards. Fix your game.
