You can no longer get the block of amethyst when mined with the proper tool. Silk touch doesn't affect the result either. The block of Amethyst hardness has changed as well. I thought this might be a bug since there was no mention of it in the Patch Notes.
However, blowing it up with TNT does drop the correct amount of Amethyst blocks.
