[Boy Blunder]

Recently picked up a handful of miscellaneous DCUC figures (Golden Pharaoh, Star Sapphire, Nautkeloi, and The Shark), and noticed that Golden Pharaoh's got some surprisingly tight joints. For the most part, they're not worrisome, except for his hip swivels - neither of his legs will do forward/back movement well, nor will they stay in position. I can't see the pegs very well, but they look like they may have some stress lining.

Is this a common issue with the figure? What are some solutions for fixing it, if any? (IE a hot-or-cold water treatment, or if I have to actually crack the figure open for this one)
