Minecraft Version: 1.12.2

Used mods
LogisticsPipes version: 0.10.3.14
Railcraft version: 12.0.0

Error on server startup

java.lang.ClassNotFoundException: mods.railcraft.common.blocks.machine.alpha.TileRollingMachine

Analysis
I think the issue is on this code line:

The code tries to load the class named:

mods.railcraft.common.blocks.machine.alpha.TileRollingMachine

But the namespace has been changed in Railcraft:

mods.railcraft.common.blocks.machine.equipment.TileRollingMachine

I don't know if there were other changes in Railcraft or if only the namespace itself changed. This should be checked and fixed.
