Rank up i was suppose to get 40000 crystal got nothing
The rewards for ranking up have been moved to the Special Missions section in the HTML5 and Mobile versions of the game. To claim your crystals, simply navigate to this section in either of those versions of the game, and click "Collect."
If you don't have the client installed already, this article can instruct you on how to do so.
Hope this helps!
