I think that’s a normal defect on Cody. I got one of these new for my son when it was first released. He’s had it in one pose the whole time and the left arm is loose.
I won this 1/4 Fett (as is) on eBay for just under $45 shipped. I’m either going to make a Mythos-like version or mod it so I can put the Temmura sculpt from my BOBF on it. I’m leaning towards repainting the armor to look post Sarlacc.
