Wily279 scene character posture error

[SPEED_DAYUM_DOGG]

So I have been collecting Wily279's works, and I have some scene cards that I use to play it on my KK.
At least few months ago, there was no error or whatsoever to the scene.
For example, a scene called "Marianne and Hilda" were displaying properly, like scene card shows.

However, after returning back to KK, I noticed that character posture for this scene has been broken like this:

The girl with blue hair is still properly functioning, but the girl with pink hair is having a trouble, such as head looking at wrong way and keep moving by its own while other girl remains at its position while play button remains untouched.
This scene isn't the only case:
(Rapi Scene)

(Tearju Lunatique)


Someone told me that this looks like a NodeConstraint issue, so I went to NodeConstraint and deselect/select many things, and for some scenes the nodes were the problem, but I couldn't really solve this issue. Does anybody with Wily279's scene have this issue as well after updating to RX21?

Okay... found the scenes and figured some things out:

For the Rapi scene, simple disable (or delete) the cf_t_shoulder_R(work) -> cf_j_head node constraint. If you want her head to not sway back and forth, disable all node constraints, "use current" on link rotation, update current, then reenable ALL the node constraints.

For the cowgirl, same thing.

As for the harem girls... I played around with things for a while until I said "fuck it" and just edited the same shoulder node constraint. So, here's what you do:
First, disable all constraints for Valentine, the bottom seven, so she isn't bouncing around.
Then, select our new favorite shoulder constraint. Enter the following values in the link rotation coordinates: 340, 270, 340, or something similar to your tastes. Click on "Update selected".
Reenable all node constraints.
That should give you a reasonably similar look.
