Has bird healing AI been nerfed?

[KisaiTenshi]

Or is this a glitch? I see my HP progressively decreasing from 80 to 0, and the bird's just chillin' there not doing anything. Healing Stance is turned on so it should be healing around 70% mark.

Or is there a hidden MP gauge for bird we are not aware of?

Mine has no problem in Free Stance. it will spam Choco Regen as long as I'm losing HP.

I think the active problem is telling it which stance to use, because if you tell it to do a specific stance, it uses a subset of it's AI rules, eg "if player HP less than X%, use Choco Regen, if player and self less than X, do Choco Medica"

When it's on free stance, it will always attack your target until you lose enough HP.
