Special Paddock Gate & Stable Stall Door
Only Horses that are mounted or lead* by a Sim can go through this Gate/Stable Stall Door.
This Gate/Stable Stall Door is a clone of the Horse Ranch "Paddock Gate"/"Stable Stall Door". This cloned Gate/Stable Stall Door is locked for all Sims, Pets, Farm/Ranch Animals except Horses that are mounted or lead*. This way you can build a Paddock or Stall where Horses cannot leave on their own, but still go through it, when you want to ride with them through it or lead them through it. I also added a temporary hidden 15 minutes Buff to the Horses - Care - Call Over Interaction, so they can go through it, when you call them over.
I added an Option to "Allow/Disallow to go through the Special Paddock Gate", which let's you choose specific Sims, who will get a hidden Trait & Buff. This Trait & Buff whitelists them to go through the Special Paddock Gate/Special Stable Stall Door.
*To lead a Horse you need the Lead Horse Mod downloadable here!
