King zeroed out all my boosters today. This is the second time it's happened. The game didn't crash, I didn't get a new device, the program just zeroed out everything. It's King's fault, they have software glitches, and their attitude on these forums is "you should have used the boosters, you shouldn't save them." But they expect us to enter competitions and special events. Boosters are the best way to compete.
I think I'm just going to zero THEM out and uninstall the game. Hey, no more ads! And I was at level 11,000 plus. To heck with them. It's just a game.
