Has anyone completed ALL of the achievements? I have done 3/9 and most I should have finished over time with normal play... but I don't see how I'll ever finish the "Buy Decorations!" one. I have bought everything I can. I'm at Level 6: 250/500. And the only way I've gotten there is clearing out my restaurant to buy as many as I can of one thing. It doesn't give me the option to sell the decorations back, so I can only purchase what fits. Its really a pain and there isn't enough options of items purchased with coins for that to even work. How did they anticipate this being achieved? Or is it supposed to be impossible without spending tons of gems?
