Play from the previous version to the current archive and restart the game by clicking on one of the options on the far right.And Cami.There's a crown on it.All the goods are exchanged for grass.How can I get back to my previous Saved？

I'm afraid there is no going back. Getting a crown starts New Game+, with the crown providing a permanent income bonus for specific resources. If you are willing to use the resource cheat, though, it takes no time at all to get back every character, besides the snake lady.
