It's funny because I seem to be in an unlimited sale since September. If it goes away, the next day it is back. I purchased gems earlier in September when I was in the hospital to help increase my game and give me something to do during treatment, and after a gem trap I decided never to buy again, as I find it unethical and a terrible mindset for a company to have, so will only play for free and enjoy the game without giving them anything in return, a stance I know several players have taken. Since then it seems the sale is just always there which I find ironic.
But just today I lost 100 gems, and I try to be so careful (serves me right for trying to save up to buy something nice I guess as I really wanted the fortune teller tent so decided to go for it and save) and nothing I can do about it, and those were 100 gems earned through the game and took a long time, so feeling really bummed right now about it. A simple confirmation button is all we are asking for and I know so many players would be willing to buy gems again.
