okay well I "fixed" it now.
EDIT: For anyone seeing this - I have released the "2.0 version" (Double Speed Belts 1.2.0) just a moment ago. This was a bandaid solution, but it is working on my end... no idea how it will behave for anyone else, especially with any other mods. But as far as the 3 vanilla belts and the new 4th tier DLC belt, it is indeed working. Meaning you now have belts moving up to 120 items/min.
If you find any issues, PLEASE share them - make a new post and we'll see what we can do. Again, I'm a total idiot and have no idea what I'm doing. So fingers crossed it just continues to work. :)
