Another glitch this morning. I have 2 silk factories that have blue butterflies on them. They're so gorgeous that I want to upgrade the others as soon as possible ... those still have the white skein of silk on them. So anyway, I upgrade one ... and suddenly I ask, "Where's my butterfly? They were the same level ... I checked and double checked, but no butterfly. I didn't recognize this one, so I checked the wiki and found that it looked "almost" like the one ahead of that but not quite, so I think it was a combo of the two. I should have gotten a screen shot, but I just backed out and reloaded, and there it was ... my butterfly. So all is well, but it was strange.
