Moss no longer spreads to stone when bonemealed

In my long term survival world I can no longer bone meal moss converting nearby stone to moss. I noticed when my moss farm broke after the update. I then confirmed by taking a moss block and setting it directly adjacent (touching) to a stone block and attempted to bone meal by hand, and nothing happened. The bone meal was not consumed. I have not attempted this with other stone variants. It might also be affecting azalea growth although I may just have very bad luck in that regard. I went through a stack and a half of bone meal and the normal azalea would not grow on dirt.
