I deleted a group, and was being lazy, just wanting to put the pets from it in a different group from the dropdown menu. All four pets are missing. It still tells me I have 11/20 pets, but I can't find them in any tab. Am I supposed to be waiting a minute for them to appear, or is this a bug? 

.... Help? 

No, the pets from deleted group should be automatically and nstantly moved to "No Group" section. There was some kind of glitch and your pets stayed bound to the old group which was deleted. I moved your pets to your No Group group. Sorry for the inconvenience.

Thanks for moving them for me. :)
