Ah, sorry, I misread that.
Ya they have been spawning forever... have you been looking in the Fel patches? Thats where I got most of mine, and I never saw a single red once. I have the complete collection of names in both of the styles (total of 170 jacko-lanterns). I also have an additional 537 jacko-lanterns I have been saving in case others want to complete their collections. I stopped even checking the patches a week or 2 ago.
