If you break a block underneath you with efficiency tools of any kind sometimes you will get stuck in a block.

x. I will provide video proof if necessary to show you this this problem was not fixed. It was fixed for one snapshot but then it broke again and i still get stuck in blocks.

How to make it happen -

Step 1 - Pillar up 20 blocks

Step 2 - Break under yourself with an efficiency IV and Unbreaking III Pick

Step 3 - You should be stuck in the air gliching about

For any videos that I have seen it has not been happening to them and i have made sure im on the same version as them.

Thank you for your time and please fix this soon
