Neighborhood Sims keep taking their puppies to a supernatural hangout in town. That would be fine (I originally had some pet objects there, with witches' familiars in mind) except both entrances have stairs, and the puppers can't get back out, so I end up getting spammed with routing failure messages from Overwatch until I go reset them. This continued happening after I removed the pet objects. Is there a way to ban Sims from bringing pets to a specific lot, or do I have to go into tuning and block them from Supernatural Hangout lots entirely?

Restrict the species or a caste for baby animals using SP's Lot Options. GoHere is required to be in place for this to work, as is probably a save, total quit, and reload, but then the sims carrying their puppies should not be pushed to the lot. It's not a brick wall type of strategy, some might still get in, but this is still what I use to keep children (including carried toddlers, babies) and animals out of certain clubs and nosy grown-ups out of teen hideouts where they have no business being, etc.

Some are definitely still getting in, but the caste is getting applied properly (I checked) and I think the frequency of stuck dogs (my inactives clearly need to learn the joys of cat ownership, because I've hardly seen any) has gone down. Thanks!
