When you till a dirt block, it pushes you off and won't let you stand on it. Noticed it when I walked from my waterlogged spruce trap door onto a tilled block with a melon stem. Recreated the bug in my base without the water and without the trapdoor

Seems to not happen when surrounded by solid blocks
