De-Synchronization of animation and parented shapes.

[nuxttux]

Friction rc2 AppImage on Linux Mint 22.1.

Hi - I don't know if this is a know bug, but every now-and-then there's a de-synchronization that happens in the rig or timing of the animation between different moving parts. With the occasional breakage.

Sometime it's not even animated, but objects move or load at different time.
In the example video, the lower arm (on the left), has no position animation, instead it's grouped with the upper arm, and that group is being rotated.

I've disabled Preview Cache to test it and it still happens at times.

I'm using expressions to capture the rotation of Nulls and applying it to groups. The influence sliders of the parent effects don't currently work, so I cannot manage influence through them.

Some animated objects won't move until I scrub back and forth on the timeline, while most others stay synchronized.

The arm on the right lags behind, so does the hand.
The objects with the most lag have the Bled Effect applied to them, placing them in front of the face and the Switch.

Is the lack of influence from the influence sliders of the parent effect a known bug?

Follow-up.

The issue with the upper and lower arm on the left was fixed by applying the rotation expression to the master-group containing both the upper and lower left arm.

The hand on the right still twitches however.
