Triangular Rice Ball?

I don't even know how the hell it even works in the first place. I thought it was supposed to feed our imps for us, but it doesn't even do that. I'm thinking it's glitched or something.

EDIT: On another note, has anyone's imps ever gotten sick since the profession update? Mine have yet to become sick, and yet they would get sick every half hour in the test server.

Mine's been sick many many times.

But yea the riceballs never worked. Not even in Testpia.
