When they are all in the resort?

It's kinda random because I think the server that controls that is spazzing out. They usually just go from hungry-bloated adn happy-sad It should return to normal c:

Yeah, right now, there's a glitch involving hunger and happiness. They were stuck at bloated and very happy, but now, they're starving and depressed, no matter what you do.

It should be fixed soon-ish, though.

Thank you, both. They are all back to bloated and very happy.
