I just bought a second hand SoC black ox. It was supposedly hardly used. The figure has some kind of drop down hips feature, for more articulation, where there is a large diecast aassembly with two hinges. The entire hip assembly is held in at one point by a small screw (red arrow). After taking it out from the box, I tried to drop the his down, and heard a loud crack. The two legs are fine, but now the entire hip assembly is loose. Any advice? Anyone else faced the same problem?
