I just noticed a glitch in my game. I have an Android device and an Apple device. You can link your game via Facebook and play on both devices. It seemed to work fine, other than collection items didn't transfer between games, but the missions, daily challenges, available emojis, and coins all transferred between the devices without an issue. I finished the item collections on my Android device, so I've been playing exclusively on my Apple device lately. Yesterday, I played on my Android device for a bit and then when I went back to the Apple device, it asked me if I wanted to load the game from the Server or the one that was stored on the device. I selected Server (like I normally do) and all of the usual stuff transferred just fine. However, the item collection reset back to as if I hadn't collected anything on that board before. I was collecting stuff on the "Outer Space" board and had about half of the items collected. After switching devices, it went back to 0 out of 215 items (the Android game was fine - it still shows all boards as being cleared). So, just something to keep in mind if you play across platforms...don't switch devices until you've just finished collecting a board!
