When right clicking grass blocks with bonemeal, you make tall grass and flowers. Ran into this bug a while ago when trying to fill a handmade field with tall grass and flowers, but right clicking the grass blocks kept making double tall grass and it looks awful. Trying to clean it up leaves patches of missing grass, bonemealing these patches just makes more double tall grass.
You can already right click regular one block tall grass to make double tall grass, if this is a bug, it really needs to be fixed. If it's not, why was this change made? I can't even use bonemeal anymore for my large fields as I do a lot of terraforming, really frustrating issue.
