Hi @keyser_soze, sorry that your message
wasn't picked up before now. What you were getting in your game was a failed test! The studio decided to test new levels that were not released to the public yet. Players were randomly chosen for this but after the first couple of weeks it became more of a nightmare. My game stopped syncing across all platforms. I play on Windows 10, an iPhone and 2 iPads and they were all at different levels. So the studio has not stopped this.
Currently the last level on mobile devices is 4430 so you are up-to-date now.
