Structure "glitches" (deformed)

[thefavero]

Hi Duduf, many thanks for your hard work!
I'm using Duik 16 with the last (valid) release of AE 2019 on OSX 10.13.6 on a MacBookPro late 2013 with 8GB of RAM
and I've this issue:
sometimes, expecialy when I make the scrubbing on the timeline, the
structure of the character that I've rigged with autorig "goes crazy", it
deforms itself, especially the pelvis bone that becomes a lot larger, and
the layers that are parented with them makes the same. I use the continuous rasterization on the layers. The bones of the
chest folds on 90°, the hands become smaller, etc...
At the same time, a hundreds of expression errors come up, but sometimes, if I
do double click on the magnifier of the orange bar with the errors, they
desappear.
Finally, if I relaunch AE or reboot the Mac, the errors desappear and the
character back normal, unless I do scrubbing or launch a RAM preview.
Somethimes I solve removing the external shadow of the level styles, or
changing the degrees of its angle, or deleting the memory and the cache.
I send you some screenshots of the normal character and the "glitch" version.
Please, let me know and many thanks again!

I attach here others two screenshots of the character "in action": these are two sequential frames, where in one the character glitches. Here I used also "D camera. Many thanks for your help!

Also here - In the screenshots - you can see how much the hips bone/locator deforms...

Weird, looks like a bug in the scale, but there's nothing there with the way Duik rigs characters...

Does purging the cache change anything?
Could you send me the project for testing?

Hi, thanks for your response. Not every time purging the cache resolves. How can I send you the project? It's quite heavy. Thanks!
