I have played Candy Crush since conception and am on Level 9000+. I just went to play my game and I'd been booted off (logged out). When I logged back in, the game looked different and all my boosters were gone... including the ones I paid gold bars for! This exact same thing happened on Farm Heroes several months ago and I had to start from scratch. King keep sending automated emails telling me it's not their fault, but if I do nothing, it's obviously a fault in the game. I'd like King to at least credit me some gold bars so I can buy my boosters back, but they never personally respond to me.
When you've dedicated years and years to a game and the creators don't assist when the game malfunctions, it makes me wonder why I continue playing.
