I see a pretty normal amount for block 22125 for myself, but in the last couple hours, the estimate for the current block dropped from it's normal number to about 1% of normal.  It's still only showing about 2.5% of the "normal" value per block.  And, my average hash rate in the last 60 mins, displayed, is as good as ever.  No issues.

And this block has been cooking for more than 12 hours, it's only in the last couple hours that the estimated dropped away from it's normal range...
