In my system, V4 hair and clothing props, as well as her jaw-teeth parts, lose their parenting now and then, and they lose it every SINGLE time I do a sim and Point-At is activated for her eyes.  The issue pops up in P6 as well as P7 (though more frequently in P7) so I have tossed her into cold storage for now.

I've also tossed P7 aside for now since this parenting loss actually occurs with some of the older V2 characters I've gone back to using.

There were many things I liked about both V4 and P7 but I've abandoned them, at least for now.
