it's not fit with the mod " Ultimate Belts "!!!
it's suppose to be twice time speed in every kinds of belt, but it's not!!!
Can you fix it?
Cause you said that it can fit with any other mods, lol~~
Done!
Please note that you must slow down items near assembler machines, you cannot use inserters with ultra-high-speed-belts. Just use slower belts near of them.
