I also use that too but for some reason some times the vars don't load. I use var browser and when i install anything from it and then re scan with browser assist and load the installed atom or anything then i get error logs for missing items. But after restarting vam ofcourse they are shown then.
it doesn't appear as a scene cos theres no scene in it. scenes will have a folder structure like this Saves>scene>random_scene.json. all this has is two plugin presets and nothing else really (thats important). theres also a preview of an appearance preset, but preset itself is missing. are you sure you got the right var file lol? cos if not u got scammed
