Had the same problem. I did everything in my power to try and find out why my main was gone, but soon enough after trying to get into the map patch again with one of my other characters (resulting in the game crashing), he too was deleted. I have a good feeling it had to do with the map. Sad to say I have to remake my main but if they're able to fix whatever happened then I'd be more than happy to get the two back.
