This year, I had the bright idea to crowdsource the rosters. This worked pretty well, except that about 215 players got messed up in the last two days of the beta. I'm not sure if it was a prank or an accident, but I've fixed it for Version 21.01.
You can download and Version 21.01 here. I've locked down the roster file for now. So if you have any corrections, please send them to me at firstname.lastname@example.org. Thanks!
