Could be, but I have unrelated dragon pairs and they haven't been producing a lot lately, either. The maximum number of eggs seems to be currently set at 1, and a lot of times no eggs at all are produced.
I was considering putting my dragon info into a GEDCOM-compatible program like SeeGEDCOMX, because I've sort of lost track of which ones are related, etc., but what a nuisance to do all that typing and clicking. I suggested an export tool as a dragon cave site feature, and naturally the other folks on the dragon cave discussion board jumped all over that as being too resource intensive.
Yeah, sure, a formatted text download of the contents of your scroll would be too much for the server, but generating the "incubator" images is fine, right? I hate dealing with people who can't (or won't) actually read a suggestion before reacting to it.
