*breaths in*Sorry if I was unclear, I meant physically remove the center caps and put them back on in the positions I listed.
Ok is swapped two center pieces(R and Y), though they were in the correct color scheme, this simulates swapping tow centers. I will know look and know it is impossible, as i need the ry edge flipped which is simple. but then look at the piece structure there is no WY piece. So by swapping centers, you are making it impossible to solve
Then remebers this guy probably had the cube in the color scheme beforehand and now i'm being stupid
