In the past twenty-fours several players have reported an issue with their game. Their progress had been rolled back, causing them to lose some levels.

Little is known about the issue, but the developers are aware of it. If you have experienced this issue, explain your situation on the EA Forums, as it may help the developers figure out the why this is happening, and how to fix it.

My personal advice, for those affected by this rollback; stop playing for a few days. Hopefully it won’t take too long to get this sorted out and bring everyone back to their proper levels. From my initial observations, it seems as though this error has affected primarily higher-level players, though this could just because the sample size for level 37 players is much larger.

If your game is unaffected by this issue, just keep calm and carry on. Though it might be best not to visit your neighbors while this issue is under review. It isn’t known if this issue and the stacking glitch are related, but is certainly possible.

Update: EA has apparently found the source of the issue. Any users who have experienced this issue should find that their games back to normal within the next twenty-four hours.
