When using dispenser to bonemeal grass there is a chance that the game will crash. I know that there is another report like this but when I look at it it was back from 1.13 and it was said resolved but it is not.

Procedure to activate the bug 

1. Go to a dispenser and place bonemeal inside.
2. Place the dispenser next to grass(which means the dispenser will bonemeal the grass.)
3. Activate the dispenser

THEN THE GAME CRASHES

I would be happy for you guys to resolve this bug

THANK YOU
