The new redstone blocks (and some old) are all unable to power lamps.

Just need to update your list of redstone materials :)

this.redstone_materials.add(Material.DETECTOR_RAIL);
this.redstone_materials.add(Material.REDSTONE_WIRE);
this.redstone_materials.add(Material.REDSTONE_BLOCK);
this.redstone_materials.add(Material.REDSTONE_TORCH_OFF);
this.redstone_materials.add(Material.REDSTONE_TORCH_ON);
this.redstone_materials.add(Material.DIODE_BLOCK_OFF);
this.redstone_materials.add(Material.DIODE_BLOCK_ON);
this.redstone_materials.add(Material.REDSTONE_COMPARATOR_OFF);
this.redstone_materials.add(Material.REDSTONE_COMPARATOR_ON);
this.redstone_materials.add(Material.DIODE_BLOCK_ON);
this.redstone_materials.add(Material.LEVER);
this.redstone_materials.add(Material.STONE_BUTTON);
this.redstone_materials.add(Material.WOOD_BUTTON);
this.redstone_materials.add(Material.STONE_PLATE);
this.redstone_materials.add(Material.GOLD_PLATE);
this.redstone_materials.add(Material.IRON_PLATE);

Turns out this still doesn't fix the Redstone Block on a piston moving towards a lamp.

I've looked into the BlockPistonEvent but can't figure out how to get that to work with the plugin.

Oh whoops Stone/wood Plate have config options and don't belong in this list. But the rest do. Especially wood button and redstone block.

Got it!! Just need to add

this.redstone_materials.add(Material.PISTON_MOVING_PIECE);

to the list as well. That is the item on the end of a piston. (Not the wooden part but the actual block that it is pushing. So in most cases this piece would be a redstone block)

Richie... Are you ever going to fix this?
