Missing Mystery Mountain?

it will be back but why not enter some of the community contests here (link is below my signature) you get a chance to win gold for your game 🐣

It was removed during Petopia in December and it is for the same reason this time.

The trouble is, if they keep too many events running, those who don't have the latest device have game problems due to the memory usage. We had many players during the halloween petopia that could not open their games at all. So while I understand that might not affect you and so you're annoyed by the decision, this would seem to be the best decision for all players.

it does I'm afraid but that's to help everyone keep a playable game rather than have everyone not be able to play for weeks. Which has happened in the past.
the levels are in the process of being updated but they are in the testing mode now so hopefully not too much longer.

aw I am so sorry. Do you check for updates on your device regularly and have at least 2gb free space?
welcome to the community though!
