So uhh, in an attempt to track down a bug with orphaned accounts and games not being cleared after completion, the database ended up getting corrupted. All registration info was lost, so you'll have to rereg your accounts all over again. Server still works, and any D2 characters should still be fine since they're stored locally.
Apologies for MySQL being an absolute piece of shit as usual. Next time I guess I need to make a backup before even daring to poke at the DB.
