I tried searching by sitting on the Reiflem page and right-clicking the Reiflem link to open a bunch of new tabs, which I would then cycle through to see if any Kurrabi eggs had shown up. I got one this way and went to the hatchery to incubate it.
The only new egg I had was an Otachie egg, not Kurrabi.
I thought maybe I had somehow picked up an egg from the wrong tab, so I tried this method again. This time, when one of the tabs yielded a Kurrabi egg, I made sure I clicked it and sent it to my hatchery. But a second time there was only an Otachie egg, not a Kurrabi.
I deleted both eggs, and I'm assuming that this is a glitch of some sort- possibly related to the manner in which I searched?
