Might have had the same thing happen to him that happened to Elwood McCarrin. He disappeared for a few weeks even after Mesanna had mentioned that his disappearance had been "fixed".
So, I sent a PM to Mesanna, which she replied telling me that Elwood would return the next day. Next day... Yo! Elwood... how was the holiday? Back to his same shenanigans...
Give the PM thing a try and see if it helps out...
