So uh... I have a user banned from all of my servers for some reason. This user isn't supposed to be banned but every time they try to join the server, it says they're banned from the servers. I try going to SourceBans but nothing is shown there. Their Steam ID isn't in the banned list so I'm not sure what could be broken here. Obviously, something is messed up. The thing is that I honestly have no idea what that thing could be.
Could someone please help? This user has done nothing wrong but they're banned anyway and I want to unban them so they can have a good time with the rest of the community.
Edit: Nothing is in the banned_ip.cfg or banned_user.cfg files. They're both completely empty.
