What I expected to happen was...:
I was trying to use bone meal on a cactus so it grew faster, it didn't work, so i tried throwing the bone meal on.
What actually happened was...:
When the item (bone meal) made contact with the cactus it was eaten by it/ disappeared on contact.
Steps to Reproduce:
1. Place down red sand.
2. Place cactus on red sand.
3. Use 'Q' to throw item onto cactus. Item disappears.
That's not a bug they've been able to do that since they were first added to the game.
