Amethyst dont grow

Hey there!

I am unable to reproduce this issue in 20w51a. In the screenshots you've provided, I've noticed that you've placed both a block of amethyst and a budding amethyst. Just to let you know, amethysts will only grow on Budding Amethysts and this may be the reason as to why you are experiencing this issue. Please let me know if this is the case, however.
