Re: No townies moving into homes?
@LeelaBabe I recently finished the Alphabet Legacy, so I know exactly what you are seeing. Every town, except the one your family currently lives in will eventually die out and not be replaced by new households in essence giving you ghost towns. It's lonely and sad.
I've never been able to get townies to refresh in worlds by visiting. I do not know if this is by design. I assume it is since only your the world your sims currently live in is populated after the original households die.
Your current world should be populating with households moving in. It's slow, supposed to be once a sim week you get a new household moved in. Only your current lived in world is affected by repopulation.
If you click on a house in live mode, you will get the option to move a household in from the library. Moving a household in this way means their funds don't count and you can move anyone in you wish. You do have to have an active sim in the neighborhood you wish to populate this way.
As for the blank names are they in world and blank? Or are they in manage worlds and blank?
In world is probably a sim that was special, like the flower bunny.
In Manage worlds is probably sims that were in University Housing and were booted out into their own households. The game does not give households that are separated this way names. I am uncertain if that is a bug.
