looking at the bottom of my cube, the 2 pieces marked O are swaped
sometimes, so that the face is still a solid color, but the sides are
swapped. [ ... ] I can't figure out what causes the swapping.
What is wrong is that *one* of the inner planes [marked 1 & 2 above] are a
quarter turn [i.e. 90dgs] out of phase.
1] The way I solve this is to turn one of the planes a quarter turn, [to
get, for example the following]:
>X|O|X|o|X <--(Where "o" is the other face of the "O" above.) >X|X|X|Y|X >X|X|X|Y|X >X|X|X|Y|X >X|X|X|Y|X ^ ^ 1 2
2] Then, to keep things straight in my head, I then "mark" the new position
by replacing the center cubies in the turned plane to their correct
positions (being careful not to mess with anything else --particularly the
>X|O|X|o|X >X|X|X|X|X >X|X|X|X|X >X|X|X|X|X >X|X|X|Y|X ^ ^ 1 2
There's a relatively simple operator to do this, which I leave as an
exercise for the reader. ;)
(It's probably better to do this to all affected four faces, but you can
save this until you have solved the edges.)
3] This leaves you five inner, non-central edges to solve. But it should
be straightforward, so long as you be careful not to mess up anything else.
