Recently I noticed some things the Candy Crush Jelly game doesn't do.
It doesn't add all the moves when you finish the level into specialized Candy to then make it possible to get three stars. It used to do this but not anymore. Making it seemingly impossible to finish levels with three stars OR you would have to try and absurd amount of times to get the three stars.
There's also a bug with the game where some specialized candies won't do the desired effect or it does the wrong effect.
When connecting some candies to and objective sometimes the objective that's in the way won't decrease in health or be destroyed. This is rare though and I've only seen it a handful of times.
