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

I have this issue but in Ravenwood with the Order of Lenore. 

Also Edith keeps being duplicated with a random grown npc standing next to the well and having same social interactions when clicking on them. It's a 50/50 shot of catching Edith there and not a random npc. 

Edit: I'm playing same save as I had before the update. 

Edit 2: Now the same is happening with fairy council npcs, mainly Care Ren has a different npc in her place from time to time and also Apothecary dude get's switched with some random npc.
