This makes me want to see what Darth Editous did in his version. I know he made a fix as well. May have been the exact same thing. I'm going to check...

Ok, he didn't recolor the one on the left, he just made it so you can't see the R2 that's in front of the gang. So basically, it's the way they filmed it and you just have to pretend R2 absolutely floored it to get around that corner. ;)
