Items glitch through blocks

Put the summary of the bug you're having here

What I expected to happen was...:
After I mine or break a block, it would drop in front of me.

What actually happened was...:
Blocks were bouncing around and even glitching. Blocks would be either outside of a block, or at the top of blocks if I were unground.
