[2021] "flutter resting" causing fall problems?

It *could* be but my instincts tell me no. The resting flicker isn't really a bug. Rather, it's the underlying state machine cycling through various states which is perfectly acceptable as that's how it checks the entity's priorities. And, when the entity is in the idle state for 1 frame, the resting status is added. I just need to delay the resting status so it is only added when they are idling for longer.
That said, I'll do some testing in this area just to be safe.
