I am just starting to use Advanced Skeleton and when adding Parent Constraints to some Extra Controllers, I noticed these Constraints will be partially modified once I rebuild the rig. See the attached image. The constraint on the left shows you the settings and connections I created. Once I rebuild the rig the constraint changes to what you can see on the right of the image.
This is really frustrating because I have like 30 Controllers that need Extra Constraints. Adding them each time I rebuild the rig is way too inefficient. Since I am new to Advanced Skeleton I might miss some basic concept on how to deal with constraints. If that is the case, I would be very grateful if you could let me know.
