Krustyland, remember that?

This is related in a way. It used to be if you were doing friend visits, and you went to a neighbors KL, because everything else had been tapped on, and you hit the next button, you went to the next SF.
But for the last few days at least, if you are in KL and hit the next button, you go to the next KL. I've tried this out a few times. And if the next neighbor doesn't have KL yet, it will skip them and go to the next available KL.
At least it is doing this for me. Try it out yourself.
