Is anyone else only receiving K Gems in the Throwback Gift Boxes?

During the weekend events, lately it appears to only be throwback gift boxes (which is great btw). However, recently whenever I pick a box it's always 480 gems. Even when I go to the next screen where I can spend 480 gems to receive a throwback box and I still only get 480 gems. And when it reveals what was in the rest of the boxes, only one displays and then I have to restart the game as it's frozen.. Is anyone else having this issue?
