Hi!
This is a great mod but unfortunately it seems the speed values are hard-coded into the mod, so it doesn't read out the actual speed value of the belts. The problem is that we use Schall Belt Configuration to change a few details of the belts including the speed of the blue belt to make it exactly double as fast as the red one. Unfortunately the Belt Sorter ignores these changes :(
So the most easy way to implement this is to read out the belt speed values and make Schall Belt Configuration an optional requirement so it loads first.
It would be great if you can implement that. Thank you!
