i have a simple code that im trying to use to access saves in json. my folder structure is

and the files are in the tim folder. my code is TextAsset o = Resources.Load<TextAsset> ("saves/tim/basics");
and o is null. i then tried moving basics.json out of the tim folder so it is just in the saves folder, and then changed the code to TextAsset o = Resources.Load<TextAsset> ("saves/basics");, and that worked returned a textAsset. is this something im doing wrong, or just a limitation of unity?
