Okay, so I have recently bought a
[Moderator: KO] Mirror Cube, and it worked completely fine, but... After about 2 weeks, I find my cube scrambled on my table (My brother scrambles them all the time), I solve it, and one center is twisting 90 degrees, to where the little lines on it (Almost like aluminum brushing), don't match up with the actual cube. It does this to one center though... But, I can't do a 2 center twist, because it's one center, and I can't do a 180 twist, because it's turned 90 degrees... He could have popped it and put it together wrong, but I don't know. Is this a parity on the Mirror Cube or do I have to take it apart?

The lines show each of the sticker's orientation.
I have checked every single side of the mirror cube, and each center is rotated correctly except for the one center that is in the picture. Do I have to take it apart, or is it a parity? If it is a solvable parity, please provide algorithm, or at least how to fix it while solving, that would be nice.
