We've had reports that on the Harvestgain world, that all the NPC's and even the lifestones! have upped and left Qalaba'r, making it effectively a ghost town.
No vendors, no doors, no signs, no lifestones...sounds a little creepy if you ask me! (Since this has not happened on other worlds, I think that it is safe to say that it is a bug.)
Rumours that Scooby-Doo and the rest of the gang have been called in to investigate could not be confirmed.
