When I holded a carrot to let rabbits follow me, I noticed that sometimes when rabbits haved to jump onto a block, the rabbit tayed jumping to the side of the block, but never jump onto the block. when Idestroy the block, the same happens with the following block. when I let the rabbits returnong a bit and let them come back, they jumped on the block without any problem. The bug doesn't happens always when the rabbits haved to jump, but it happened several times. On the screenshot, the rabbit  where the bug does happens on isn't completely visible.
