Describe the bug
Make sure to include:

1. Grass paths should not revert to dirt
2. Sometimes, on nearby block updates, paths on a "step" above will turn back into dirt and fall into path blocks below, which destroys the block as intended.
3. This wasn't a crash.
4. Screenshot included. The gap visible was a path block before, which reverted to dirt and then fell into the space where there is now dirt on the next level down once a block update occurred nearby
   

To Reproduce

1. Make path blocks in a slope setup
2. Then wait for or force a nearby block update (as when making more paths or when grass grows onto dirt blocks)
