This was my thought too. The other legs don’t just stay the same as you turn it. What if one of them is now off the ground or too far into the ground?

Isn't this a topology problem?

On an uneven surface, are there always 4 points that define a square of sides length x that are always [in the same plane]? That has to be no, right?
