It's most often a memory issue-the game is over the RAM limit, or close to it, and can't save-but it can in theory be any resource. If you don't use mods, you could download households from the Exchange (watch out for bad cc), or you could save interesting sims from other worlds and place them in your new one.Įrror 12 is an out of resources condition. If you use mods, there's a way to force "rapid immigration" of a specified number of families. The NPCs are generated by the game to fill certain essential roles, but otherwise, immigration can be slow, and besides, the sims generated will have all their sliders set to zero, so they'll look pretty similar aside from skin, hair, and eye color.

Did you download the populated or unpopulated version of Alpine County? I'm not sure whether the other two come populated or not, but many world creators leave their finished worlds empty on the assumption that players will download or create sims to live there on their own.
