Console display "No config with filename '0' found"
When the "Auto-configure" feature of a listen server is set to "No" (instead of public/competition settings), the server might display:
Will try to load config: "configs/0.config"
Warning: No config with filename '0’ found
This happens because the g_customConfig cvar cannot be set to an empty string, as cvarStrList doesn’t support it. Instead, I did use "0" as a cheap workaround. The server config check then correctly catches that non existing config file.
Replace the cvarStrList by something that allows a cvar to be empty, or expand cvarStrList to support empty string.
