Plutonium

Can someone give an explanation on how to get the mod to load while in the menu? All the changes activate perfectly fine in a match, but as soon as I exit out to the lobby menu it shows no mods loaded. I've seen 100 times to read the readme but I'm running into the same issue as perfectlemonade.
It's strange, if I join one of the reimagined servers, then it'll download the mod and such perfectly fine, and will even stay on the menu until I shut off BO2. Meanwhile, if I try to just load a local server myself it will show nothing different in the menu.
this is a wonderful mod btw, just a bit unclear how to get it up and running (I'd love to see a video guide one day)!
(if anything maybe including a full, uncut guide, or a direct link to one, or what we should be looking for in the readme would be a massive help)
