Merchant Archive

I have two vendors right now. One is fine, sitting in her proper spot in a shop in Mos Eisley. The other is not so good...

I was crafting in my basement when I heard her bark her advertisement to a potential customer. I was busy, so I didn't run upstairs to greet the person like I usually do when I'm online. About 15-20 minutes later I go upstairs to talk to someone, and I notice my vendor has run off with somewhere between 50-70 items. She's still registered on the planetary map, and the game still *thinks* I have a vendor, but I don't. Is this common? Is there a way to get my merchant back?

Sorry if this problemhas been posted. I scanned several posts and I didn't see it mentioned....
