Vet clinics don't function if owned by another sim

One of my sims bought the veterinary clinic in Brindleton Bay. They’ve employed two vets and have bought several perks. If I go to a different household and try to take my pet there, there’s no vets there to examine my pet. It’s absolutely deserted. So I have to build another vet clinic that isn’t owned so that other households can take their sick pets there to be cured. This never used to happen. The vet clinic used to still work if it was owned by another sim. It’s very aggravating. When I’ve gone back into the household that owns that vet clinic, there are no vets employed there any more. I have to employ them all over again. I have no mods or cc installed and I play on a pc.
