Agreed. I did the same to mine with 3 stacked pieces of duct tape. It firms everything up nicely. But when I move the shoulder joints too much (more than 1/4 turn)... they pop out of the U shaped sockets inside the bot torso. Also the orange collar pieces which connect the front torso to the back piece, which rest on that knife edge behind the neck, and either one will randomly pop off loose if I look at it the wrong way. Maybe I might try stacking more pieces of duct tape on the rub spot, to in turn push the entire torso upwards, thus hopefully more securely keeping the 2 orange collar connectors connected in place... ???
