Yeah, that's the spot and it looks like the earring is un-checked. That's normally the way this is done. Maybe it was hacked to un-include-bends but the weight maps are still on the pop.

Rather than de-bugging this the easiest fix is probably to use the group tool to spawn a new prop.

Zero the figure

Select the earring.

Open the grouping tool.

Create a [New Group]

[Add] > all on the new group (Should turn the whole thing red)

[Create Prop]

Give it a sensible name.

Close the group tool

Delete the original prop

Reparent the new prop to the figure's head. (Obviously don't include bends.)

Save the un-bendified prop to your library. Choose yes when asked about saving the parenting. That makes it a "Smart" prop
