EDIT: As soon as I posted this I figured out the issue. I forgot to delete the tests folder from post-processing 2, so I was getting script errors that were preventing upload.
This is SDK 2019.06.25.21.13
Whenever I attempt to publish a new world, I get an error I've never seen before that says "Could not run VRChat scene | Last built VRChat scene could not be found. Please Test/Compile Full Scene (slow)."
This error also occurs whenever I try to test the world as well. I have not done anything different with this world that I generally do with my worlds, so I have no idea what is causing it.
