*DONT BUY GEMS OR COINS!! So frustrating! Start building something and I come back and it's not built or being worked on but my gems or materials are used up and gone. This is why I don't like to buy anything in games. This has happened to me a lot recently. I never have nacre. I put my workers to make nacre and when I come back they're not working on it, I have no glass made and my materials are gone.
