Can't find Wruz Olg'lmar, any suggestions?

mysty

I have completed the three quests that Wruz gave out leading up to The Birthing Pools, then I took some time off from the game and returned recently. So I did initially find him and I wanted to finish the series of quests in the Whispering Caverns, but Wruz is no where to be found in the Laboratory. I have looked everywhere and spoken to everyone in the Laboratory. I've sent in a bug report, but thought I would ask for some help or suggestions from everyone here. I would greatly appreciate the help, been looking for him for 3 days!
