However, this event seemed to contain a serious bug.
When I opened my FarmVille 2: Country Escape app after the event was done, I noticed that they send me a message saying that they cashed-in all remaining ingredients.
I closed the app, but when I returned, my Pucker Points were gone and my ranking went up by about 15 ranks. Also, they RAIDED my farm, taking ALL my ingredients, not just the ones related to the event.
However, on the bright side, my account still seems to be functioning normally.
