I really enjoyed this game at first. Unfortunately some upgrades that I had received disappeared at the end of the season. I wasn't aware they go away, even when you've spent real $ on them. I should have read the "fine print". It is very disappointing. Don't waste your money on this game. Lots of reviews stating how expensive items are for upgrades, etc. Zynga replies with how your voice matters... Yet, haven't seen any change In regards to these issues. Time to prove it, Zynga.
