@crinrict Also yes! One lot that won't load has no families, two are community lots, one is a rental, and the other is a residential with a family.
I have tried moving all of the sims out, making them take their furniture, moving them elsewhere, and just deleting them altogether. Even after removing furniture from all the residental/rental homes and deleting all the sims in that neighborhood, every lot still won't load. I even tried playing other families, which work fine, and they can't visit any of the lots.
I'm not sure after which update this started happening, but I didn't have this problem when I last saved this file a few months ago.
