When was Shaw's credit ever removed? He's still there when the mask comes off, even though his eyebrows aren't.

Even Clive Revill's name remains on ESB, and he's totally gone .

Could have sworn I heard that in the HelloGreedo ROTJ changes video. I could be wrong though seeing as how I haven't seen that video in years. Also I've never seen the SE or the BluRay versions of the OT. The clips I've seen of the changes were sufficient enough to scare me off. That being said I could still be wrong.
