Some players face the issue where they can't get the magic ball for upgrading Totem of Happiness. The game says that the magic ball can be received after fixing the stairs but the stairs can be fixed only after upgrading the Totem of Happiness. We understand your frustration but it's not a bug in game! The solution for this issue is very simple.
You just need to scroll all the dialogues in the left side of the screen looking for an unread one. Once you read it, the issue would be solved.
We recommend not to leave any of the dialogues unread. That may lead to some pauses in the gameplay.
