Good, but has bugs – Slugterra: Slug it Out 2 Review

So I've played he first one and loved it, this one is just as great except that at random a single tile will just lock. You can't move it, and you can't move anything around it, you can match it and it can fall to the bottom but it won't go away. Is this happening to anyone else, or is this just a problem for me?
