Access to your server's resources folder via FTP (like FileZilla) or a local file explorer.
Old map data can sometimes cause "ghosting" or texture flickering when you add new environments. Navigate to your main server directory. Locate the cache folder.
Create a new folder inside your server's resources directory. Name it something recognizable, such as favela_map .
The server won't load the map unless you explicitly tell it to. Open your server.cfg file.
