Fixed, as you were

Today's TF2 update introduced a change to how SteamIDs work internally, which is why it wasn't working. I'm currently in the process of deploying a fix to all the servers.

Alright, we should be fixed across the board.

Some fun facts: this SteamID change broke the admin system, ban system, and the donator perks and countless other things that relied on using SteamIDs for player identification. Fun stuff.
