[COL] NPC roles assigned to multiple Sims (Sometimes duplictes)

I started a new save after the latest update. Game is fully updated with all packs, kits installed. Mods are still switched off since the update. I noticed that playing in Henford-on-Bagley all NPC like the groceryshopowner, mayor and the creature keeper are double in the game. The once you expected like Michael Bell and Kim Goldbloom but also a random (ugly sims with an overload of accessoires) NPC. The OG sims are fine and alive so a replacment wasn't needed.
