Subject: MC weird again 

~20 minutes ago, maybe right around the time the fb's RAID died (elog 8274) the mode cleaner started behaving weirdly again.  The reflected value is very high, even with the WFS on.  Earlier this evening, I saw that with the WFS off, the MC reflection was high, but the WFS brought it back down to ~0.7 or 0.8.  But now it's ~1.3.  With the WFS off, the reflected value is ~1.1.  I don't really understand.

Also, the PMC has been drifting in alignment in pitch all day, but a lot more later in the day. The PMC trans is 0.800 right now, but it was as high as 0.825 today, and spent most of the day in the high 0.81xxx range today.

I would provide plots, but as mentioned in elog 8274, we can't get data right now.
