Hi there, Just did the update , the gameit reset and I got back diamonds etc. However when I started to play, and it said to give the snail to the villager, that was hidden behind the large chest, and when I tapped the chest has dropped down on to my board. Because the game is still in the "teaching" mode, I cannot merge the two stones together, and when I tap the bucket, it says the board is full and I can't move on. I've shut the game down and turned my phone off and back on, but it is stuck. Any clues on how to move on? I don't want to delete the game and risk losing all my diamonds they gave back.
