How would I unban myself from my own Listen, LAN game?
Remove your SteamID/IP from banner_user.cfg or banned_ip.cfg in cfg folder.
No such file name exists there.
What did it ban then?
This is inside my own Garrysmod game. This is not a dedicated server or anything. I opened start a new game ‘Multiplayer’ on the gamemode TTT. Testing my SWEP and killed all my bots and got karma banned. There is no ban folder in cfg.
Try removing sv.sql in your garrysmod folder.
