I lost 600 rubies just by accidentally mistap on a tree next to a chest and bought time for 1 shard, I wish the game crash but it be stable for 30 mins to steal my rubies. All I can payback is voting 1 star. 600 rubies (buying time) for 1 orange shard is like selling a tire for a whole car price, sell 1 cent for 100 dollars, all people buy it are by accidence because only idiots accept that price, this game design it to steal from players. You can't sell things properly, you become thief.
