Hi Optera,

can you do more Loader with higher speed to match Ultimate Belts?

that would be very great, if this is possible.

Gives any solution for this problem?

i have the same:
(No covariant prototype to load express-transport-belt-to-ground-extended, that was saved as type transport-belt-to-ground, but is now underground-belt)

i changed all types to underground-belt but have everytime an issue
