I lost over 100 gems when a pop up for the magic oranges popped up when I was tapping my buildings. I quit these challenges. I told S8 to return thegems and take back the stupid oranges. I'm sick and tired of losing gems do to their unpredictable pop ups. One or two ...I'll let it go but over 100 and then getting my request ignore... I QUIT PLAY THESE STUPID CHAllenges because takes up too much room and S8 ignored our earlier request for a sign that asked "are you sure you want to use the gems"? So boring repeat repeat nothing new.
