I would just mark the gate as the front door since it's an option to do that if the gate is the first opening the visitors reach on the lot.I've had Christopher Steele unable to enter his home ince after he glitched and shrank to toddler height with his adult head after my active family's baby was taken away by the NPC social worker and there were other signs of corruption starting to show up in that save like married cuples turning into siblings and others becoming partners or romantic interests when they were family.
@IreneSwift -I'd just set the gate as the new front door in that case.
