Auto-Weld not working

I have similar setup and looking for the way i can animate Angular Limits, for example from 12 o clock to 9. is it possible? I found that limits locked to position it was connected.

Also, i tried to connect child (with physics) to parent (no phys) that connected to the core and animate angle for parent. It worked with Autoweld off, but then i’m getting weird shift of my child. kinda visual position changing backward from the motion. and faster core moving, more visual shift i can see. at speed 100 it’s so far behind, like 1-2 meters. seems like a bug. (5.3.2)

Core - Phys sim
__Parrent - No Phys Sim, Auto Weld OFF
___Child - Phys Sim
Phys Constrain: Child>Parrent

Please help.
Here is few screengrabs of the issue. Still vs moving
