Sorry to hear that.Just received mine. Right arm broke immediately at that shoulder joint. So that sucks. Time to find a new body.
To anyone else getting this, I strongly suggest undoing the shirt and checking the arm's orientation at the shoulder and elbow before making any attempt to move/bend it. This shoulder issue is new but Art Figure elbows always seem to be extremely tight, so one should verify they're trying to bend them in the correct direction and grasp the arm both above & below the elbow. The shoulder design is obviously not very robust, but I suspect the rigid elbow may be the real culprit.
