Oh this was driving me nuts, only with emerald proto-whelps. It made no sense that I couldn't find a single one that was P/P when I'd found probably over 100 whelps. An add-on issue makes a lot of sense. I'll have to check for another update, because I just updated recently and still had this problem.

Hey, I got Pebble just the other day by realm hopping the auto-invite groups in group finder. I did the quest 10 days in a row thanks to group finder. Quick and painless. Just sat in front of the quest giver and realm hopped til he lit up. Good luck!
