I've just soldered R18, which is on the back of the K2 control board.  
This picture is of the front of the board.  Right in the middle of the 
picture is one of R18's leads, and encircling that lead, a tilted white 
ring that looks like what was on the board, encircling the hole, before 
I started soldering.  It has lifted off of the board, buoyed by the 
solder, and is sitting there like a winning ring-toss.

What is it?  Is it bad?  What do I do now?

Best Regards,
