After about 1000 levels, I decided to link to my Facebook account. Once I did, my power-ups that you can select before you start a level (color ball, wrapped candies, etc) and the ones available within a level (shuffle, single block smash, etc) reset to zero, my progress in the Soda Cup was gone (was leading by nearly 10,000 points), and my unlimited lives were also gone (had accrued over 20 hours worth)
Sure would like to have all that back
