Rigging bug? Weird relationships between bones. My brain explodes (VIDEO+Screenshot)

He starts his discussion about it all at around 10 mins into the video…

I didnt see that this thread was living after my last visit.

Thanks mate. But that’s not what I was asking for. I didn’t ask for isolating rotation or something like that. No practical advise, just theoretical. Only DanPro understood me right but he couldn’t explain me why it works that way.

I was asking simple question. If the bone 004 really changing it’s own local space because of the constrain? That was the question
