Re: Can't talk to other sims since 7/23/2024 update
@zappnickel Please test in a clean user folder. Move the entire Sims 4 folder out of Documents > Electronic Arts and onto your desktop, and when you launch the game, a clean folder will spawn with no content. (Your saves and other content will be intact in the folder you moved but temporarily not read by the game.) Don't add anything to the new folder yet; just start a new save and see whether the sims can talk to each other.
If the new save is fine, try an existing save, moved to the new folder, still with no mods or custom content.
