In 5he flesh from bone quest meshif, at the next stop after complaining of his pipe, just stops. Nothing can be done and you have to start the quest over.
In my situation, it was because Lorath was blocked by the camel or somehow stuck there and couldn’t move to Meshif. Try lure some enemies nearby to the waiting area to attract Lorath, and he will get to the right positions to talk to Meshif.
