After the latest update, I noticed that when I select candies to move, they deselect when I actually try to move them. If it's a normal candy, it just de-selects when I try to move it (but works the second time I select it). If it's a special candy, it immediately breaks when selected. I am not able to mix or move special candies at all.
This happens specifically in the bakery, but I have noticed the special candy bug in regular levels, too. In those levels, if I click on a special candy twice, it releases. I can still move them by clicking once, but only in normal levels.
I tried to report this in-game, but the help link just brought me here.
