Bunnies don't spawn in Forests and don't eat Wheat

Wandering around in 0.13.0, I noticed that there isn't any bunny in the forests, only in deserts. It was pretty sad to know this bug, I wanted to have bunnies in my world...
Also they don't eat Wheat. I'm not sure if it's a bug or a thing that is supposed to happen, but I really wanted they to eat Wheat, since they eat your crops. Well I consider those as a Bug.
