Make sure you have this version or higher or the map will not load.You must unzip the file before adding it to your terraria worlds folder (Right click, extract all).Click the orange download button and save the zip file to your computer.Right click on the downloaded file and select extract all.Put the extracted file in the same folder as your other terraria maps (usually C:\Users\%USERNAME%\My Documents\My Games\Terraria\Worlds)Ģ.) I put the file there but it still won't load or says I need a backup (.bak) file.Make sure your version of Terraria is up to date.
