Heya, thank for you for the report but this is not a regression. The reason why the previous approach worked was due to the fact that joints never cached their initial frame and would sag/break each time they were changed at runtime. Making use of autoConfigureAnchor to pick up scale changes is a good idea and a valid usecase. As such we'll open up a internal task to add proper scale handling for joints and tie in this report to it.
Cheers,
