HELLO I just want to report that the gem events not working properly, I have chosen an avatar to dress in the challenge but instead of going ack to the next level it goes back to the beginning three times before going to the next step. there is also a problem with YOWORLD desktop. YOWORLD desktop is just a white blank screen refreshed, clean cache & cookies tried different browser still blank. Apparently, all the issues were not fixed.

I am having the same problems. I was able to do the Gem Event by going to the game through facebook. I hope that helps you. I think perhaps both the apps aren't working. Hopefully, they will be able to fix it soon.
