Well, an error occured in the user file, and it basically reverted the user file to a really old one... which meant most of the deck references were pointing at decks that don't exist. Such is the problem with an alpha, you never know what will happen. That's the whole purpose of an alpha, to fix problems.
The result, I completely re-coded the user loading/saving code to save each user in it's own file, completely isolating each user from the rest of the game (so if one user screws up, I can restore from the other feature- hourly backups, numbered by the hour and day of the week. This means i'll have 168 snapshots per user and I have to let it sit for a week for it to be a perminant problem)
Now, all of this means, I had to delete the old file (there were over 500 accounts in the old file (!), and I couldnt very well go through and check against EVERY one of the probably over 1000 decks.) I'm sorry, but it's not something I could fix without there being phantom decks and out-of-date user information throughout.
Anyway, you'll have to re-make all your characters, and re-verify, and begin your quest again. I'm sorry, I would fix it if I had the capability, but I really don't.
