I have this 12" TaunTaun at home and Han was riding on it ever since I brought this home a year ago. Last night, it topple down from my display cabinate. So I tried to put it back in display but the TaunTaun just refuse to stand up anymore. And when it does, it topple again when I place Han on it.
Therefore, I took a closer look at it and discover that both joints on its thigh are loosen from the sprocket. it kinda "spread-eagled" itself gradually when on a standing posture and ultimately topple. Now I have to use some sort of support pillar sit just between its chest and tummy. Hope that works.

Any of you folks has the same problem as mine?
