A couple of checks in the various services offered by the Family require a sim to be on their home lot. Unfortunately, this required a new check to be added to the interactions in order for them to show up on tiny home lots, as well as just normal residential lots. Thanks to Schram92 and Lumi Buttons for pointing this out and helping me corroborate the cause.
