Hey, I wanted to warn you about the server you were connected to. It is called Fastpath.
They are scammers and create about 80 + fake servers daily on the hl2dm list and other games. They steal server names and player names - making it hard for players to find a real HL2DM server.
They also steal your Steam Auth ticket for up to 5 days!
The way to revoke it is to connect to a legitimate hl2dm server. Any will do.
If you like you can download the blacklist

Stay safe and happy holidays :)
