Is this a known error in ESB?

Forgive me if this has already been pointed out, I was searching something else and noticed this in ESB. The scene when Luke first arrives on Cloud City and Boba Fett attacks him in the hall, I noticed at least one of his knee pads is on the wrong leg (different from upsidedown knees in the Carbonite Chamber). Here's the best screen grab I could get, had to pause the TV and take a pic with my phone, but sure enough, at least one of the knee pads is on wrong. Seems to me like they just couldn't get Fett's knees right in ESB lol.

Wait till you see the carbon freeze scene where his knees are upside down.

I'm already tracking that, I mentioned it in my post. I'm asking if this particular scene was already known about. It probably is, as much as every frame of Boba Fett has already been put under the microscope, I just happened to notice this myself and don't recall it being mentioned before.

It's the PP3 knee, also wearing them like this just before that scene while he's walking HIC down the hallway.
