I don't think that's it, actually. We'll be pushing a new patch soon with an update to him again. He seems to disappear if you talk to him the second time and then go into the tavern before you talk to him a third time.
We just made an update that should correct this issue, but only if you have not talked to him a second time. If you talked to him a second time in your save file, and now he's gone, I don't think he's coming back, and a new file would have to be started to see him (I'm sorry about that ><).
