I have created a merchant and I cannot get her to show up in the game. I have the merchant chest set up. faction is set up. both the merchant and the chest are owned by the faction. The merchant has the "jobmerchantvendor" faction set up, and the custom faction. The NPC shows up in the game before I set her up as a merchant, but once I set her up as a merchant, she disappears... please help.

What AI package did you give the NPC?

I had only one, Defaultsandboxeditorlocaton512... When I removed it the NPC showed up, but now it's not acting like a vendor.

If you had that as the AI package, the NPC should not go anywhere. In order to initiate conversation, I think it needs an AI package, since it has flags for greeting and stuff.

1. Is the cell navmeshed? And finalized?
2. Are you using a clean save game?
