See video description information. I also created a thread about the new launcher, but I didn't get any anwsers. But as I said, it doesn't improve the run and the map is still the same. It's just way easier to install and works with any Java version, so you don't have these old error you had. But for the sake of this run, I tested the tricks in the old Launcher and every single trick does work, so there's no problem here.
