That being said it's time for another Star Wars Axia edition moment...and this bugged me before the prequels were a glint in anyone's eye so its not a case of making the OT fit the PT. Its a case of a Jedi not carrying his lightsaber...he would build a new one.

I really don't think it's an issue. Yoda (like every other Jedi) wears his lightsaber beneath his robe, so you wouldn't see it anyway.

And if he lost it in ROTS... how would he build a new one on a swamp planet?
