Some people had mentioned in chat that on previous years any currently brewing catalysts had autocompleted at the end of the event. Is that true, or am I out of luck on the catalysts I was still brewing? I can't access the brewing page and no additional eggs are in my hatchery.

Not every catalyst gets auto-completed. The criteria can vary, but for this past summer fest it applied to anything that was majestic, fabled with any pearl (blood) on it, had a prismatic or golden pearl (greater blood) on it, or was 65% done at the time the fest closed. (x)

If any of your brews met that criteria, it could take a few days to receive your eggs because I think Krin has to do the auto-complete manually. But you'll get them soon enough!

Ah, I see. Thank you for the info. A few of my brews met those requirements, so maybe I'll get some of those. :)
