Several have seemed more difficult to me lately. I agree about this one. Today's (Feb15) 8x8 difficult and 9x9 also both seemed more difficult than usual.
I may need to tweak the generator a bit.

It's definitely possible that this solving step caused some (especially larger) puzzles to be "underrated".
