Hi, new update is here.
We recently released an update to fix a bug in the game's progress, but it caused another serious error that could teleport you (even underground!).
That's why we quickly removed that update and released a new one today. Everything should be working now.
If you have had problems completing specific tasks so far, go back to them and click on the sign/mailbox. It should be fine now!
If you have any issues, please let us know.
