I just did a move in the game where I could move one of my bees. I clicked one but then decided I wanted to move a different bee. I couldn't see a way to deselect the bee so I clicked the other bee I wanted to move and... my bee disappeared! I hope it's just stacked on the other bee but I have no idea. No confirmation, no undo, no way to deselect. 
UPDATE: The bee is gone, just got discarded I guess. Definitely need a way to deselect or at least a confirmation option.
