You can put in a Customer Service as Sizz suggested, but your missing gems could the result of a few things.

  • The timer expired and you hadn't collected your winnings, so they disppeared
  • The original stakeholder beat you once again and took back your looted gems
  • A third party attacked to claim some gems and because you were now defending the stakes, beat you and claimed your half instead


It's worth checking out if any of the above scenarios took place.
