Where did my "Yellow" go?

Is it just my computer, or did all the yellow color on the smileys previously posted disappear?? I'm just seeing a plain 'ol outline. I can, however, make a new yellow smiley

Is this a sign of a bad day to come?!
And now I have some smileys in yellow, and some not. Weird. Or a signal of Impending Doom, lol....
