I had just purchased Sims 4 Werewolves a few days before the latest Update on July 1st.
I had joined the Wildfangs and rose to be Alpha. It was just the three sims (My sim, Rory and Lou) then I could ask others to join the pack, etc.
Update happened, uploaded the game and saw that random townies had joined the pack. Turns out these townies aren't werewolf. And doing werewolf things around them, like transforming or howling projects negative reactions lowering the social status of being part of the pack and ultimately getting challenged or kicked out
I uploaded to my last save and as alpha tried to see if I could kick members out, this worked but then new townies would spawn and join in. And also lowered social status as well for, y'know, kicking people out over and over. After kicking these townies out, the option to "Ask to join pack" is greyed out with a warning that say "Non-werewolf sims cannot join"
These townies keep spawning from the underground tunnels and headed straight to the Wildfang trailer. I've done everything from turning what CC I had off, deleting save files, even uninstalling and reinstalling everything. Looks like it happens for both Packs as well, the Wildfangs and the Collective.
It's made a pretty big part of the game unplayable as again, the non-were sims are terrified of werewolf actions but still are "Part of the pack", trading gifts, going in and out of the trailer etc
