Looks like I might be able to update the availability field of the basic info for the review!
I had a look at the hinge on mine, and there are what look like very thin stress fractures on the hinge, but they don't see to change width when I move the joint, and I moved it a few times to look on both sides to see if the stress fractures got wider and thinner. Because I'm not 100% sure it's a break, I'm reluctant to apply hobby glue to the cracks.
