Recently, when I was moving my brood I found that another one of my dolls has developed a similar problem. The doll in question is a completely different than critter than the Yue, though. He's a 60 cm (barely, dude's small!) AngelRegion Tanning Kai who wasn't in the best shape when he came to me, but the abuse was mostly to the poor thing's face and not his body. Apparently, though, whatever AngelRegion used to fix the top of his leg (think hipish) to the thigh (why they needed two pieces when it's a non-moving joint is beyond me) has come apart as well. Also, unlike the Yue, he has never been tightly strung and is cuddly, floppy guy.
So this leads me to think maybe the pieces coming loose might be more common than I thought and not just a slight flaw/weakness in the new Dollzone body. Has anyone else had a problem like this? If so, how did you fix/deal with it? Below are some pics of the joints in question to help out.

Any help would be greatly appreciated! Thanks in advance!
