Maybe I'm stoopid, but I kind of need this illustrated for me.
When using 3OP+M2 and you have corner permutation parity, what do you do to fix this? I'm trying to figure out how to do this without stuffing up the edges. E.g. I memo edges. All good. Then I memo corners, and find out I have parity. If I executed corners and then did a 2/2 swap, wouldn't the edges that I just memoed be wrong?
My brain hurts.
