I will say on Swizzard's behalf that I play in another PBW game where he has been ahead of the time schedule. Sadly, in that game I have been the absolute Last turn for the 3-4 turns now. In game he responds consistently, and out of game we have swapped emails. I would more easily believe that his email is bouncing yours out of the mailbox, or perhaps he has gotten himself in too many games at once (like that's never happened to anyone)
You might try contacting him in game as well, if you have not done so already.
