Character foot wobbles on uneven terrain while mining

Build Version: 0.0.3 Alpha 23376
Description: When mining (or chopping) on uneven ground, the character's feet tend to "wobble" as the game repeatedly changes its mind about what part of the ground they should be parallel to.
Reproduction Steps: Pick a spot to mine that is uneven and mine.
Reproduction Rate: 100% when the terrain is uneven where standing when mining, but not 100% to find such a spot.
Expected Behavior: The game should "lock in" a definition of "level ground" under the feet and stick with it through subtle limb shifts during animation movement.
Attachments: A short gif of the issue.
