I recently created a new clean neighborhood, without the default townies and stuff. But I added the default vacation destinations, knowing those come with many premade Sims.
The problem is, I checked the list of Sims in SimPE and there are many Vacation locals with a lot of weird relations that I'm 99% sure that shouldn't be there. (I think they are all locals, I didn't check them all.) They are relations with NPCs like Hula Zombie, Pollination Technician, Ideal Plantsim, Therapist.
Is it safe if I leave them, or should I maybe delete the relations?
(I attached a screenshot with some of them)

After adding default vacation destinations it is highly recommended to exit a game and run Hood Checker. It will repair a ton of issues, still leaving behind 3 strange relations with bellhops. (1 for each destination). These 3 you need delete manually with simPE.

Hood Checker is available at the following link. This is a utility program, not a mod, so it does not go in your download folder. It's highly recommended to run this program after every Sims 2 session.
