As it says, I can no longer place rail on scaffolding, be it reinforced or no.
This is current for: 1.3.2 + Forge 240 + IC 1.106; rail that was placed on scaffolding prior to updating to 1.3.2 remains in place but if one of the rail tiles or one of the supporting scaffolds is broken the entire section of rail breaks and is unreplaceable.
If anyone has encountered this, and has a possible solution, 'twould be much appreciated.
