Griffin, from the sound of it we have the exact same problem. Mine comes right off whenever I touch that leg. I can't think of any solutions for it as the connector for it is very thin and fragile. Lucky it's a figure I don't really care much about.

Besides deluxe Megs broken leg, Voyager Prime's loose shoulder joint and Bulkheads broken wings, the QC issues are minimal but when scouring TF forums there appears to be a lot of QC issues. I'm glad my Lockdown has no problems unlike Gutsman's.
