This has been an all day problem! And if/when we do get back to the Facebook Candy Crush Saga, you can bet that we will have lost daily visit so that our Treat Wheel will revert back to lower number. Therefore, we will lose out on potential wheel treats! Arrrrgh.
I have been having the same issue. No treat machine showing for days, then I am set back by 5 days. Treat machine showed back up for a few days and now has disappeared again! Been playing this game for years and I'm on level 3095! But it's getting frustrating.
