BUG+4: 2r1c4=2r1c6=2r6c6=2r1c7
2r1c4=2r1c6=2r6c6=> 8r3c6
2r1c7=>5r6c7
Thus, 5r6c7=8r3c6-(8=5)r5c6=> -5r5c8,r6c6
Marty, I don't believe that excluding 2 from all of the indicated cells yields the BUG pattern. You would have only one 2 in column 6 and three 8's.

OK, thanks. I was a little nervous about my solution and was half-expecting a comment. Would three 2s and an 8 in r1c6 do the trick? (I don't know why I didn't try the 8 originally).
