It worked fine for me, just install everything the way it says in the first post.
I’d like to say that during play testing it wouldn’t be a good idea to waste too much time posting about out of place textures, or aesthetic things, like floaters etc... that can be reviewed in a local game by yourself. Instead the play test should be about gameplay;
Does it feel balanced for both teams?
Are there areas that you could accidentally glitch into?
Does gameplay around a certain flag feel too bottlenecked or too open etc...
Does it cause FPS drops or the flag bug? (It caused flag bug for me on local)
Are there too many vehicles, too little vehicles, are they too powerful etc...
Should certain kits be limited etc...
That’s more what a full gameplay test is for imo. Aesthetic things can be commented on locally.
