Ranch NPC not working

Hello!

I’m encountering a problem with the Merged Outpost With Bandit Camp prefab that I purchased. Specifically, the ranch NPC that is supposed to sell horses is not functioning correctly.
When I interact with the NPC and advance the dialogue, the purchase interface never shows up. Instead, the conversation abruptly ends and I can't buy horses.

I have tested this on my server and confirmed that other NPCs/vendors load correctly, but this specific NPC does not work.
Please let me know if there is a fix, update, or any steps I should take to make this work.

Thanks in advance for your support!
