@ mathman,

No need to turn of IK or zero the figure.

To fix Jessi (not JessiCasual), first make a backup copy of the file, then you need an uncompressed version (cr2 not crz). Open 'Jessi.cr2' in a text editor, Search (or "Find" in some text editors)  for the second instance of the string "actor hip:1". From this point on (not before), use your text editor's Search & Replace function to replace every instance of the string "propagatingScale" (note the upper case "S") with "scale". Note that you are also replacing "propagatingScaleX" with "scaleX" etc.

The fix for JessiHiRes is the same as for Jessi.

For JessiCasual, you first need to replace every instance of "scale" in the BODY actor with "propagatingScale", there are four instances to replace "scale", "scaleX", "scaleY", and "scaleZ", so "scaleX" gets replaced with "propagatingScaleX" etc. After you have done that, proceed as above for Jessi.

Note that I'm talking about the problems that I found in my versions of Jessi, I don't know if she was fixed in P7.
