Here is the end of almost 2 hours of just trying to get a campaign to load. This only has class mods no level mods because we were just trying to test builds for our campaign I've been building since launch.
I assume that I have wasted all the time spent building that campaign since something as simple as this wouldn't work.
Here is the video of our attempts to get a campaign to load.
