A glitch where you can noclip through the ground. This glitch happens when you till a peice of dirt with no blocks beneath the tilled dirt. Once you trample the dirt and stop jumping when it becomes solid dirt, you then no-clip into the ground beneath. This glitch can also work with blocks beneath the dedicated block you want to till. Another thing I noticed messing around with this glitch is when you crouch in the block while it's tilled you are unable to uncrouch (this is when there are blocks beneath the tilled block).
