Schematic creation/save tool does not properly register non-standard blocks (At least not Ae2 nor Ender IO ones listed)

Minecolonies version

Version: 1.12.2-0.10.1-RELEASE

Expected behavior

The save tool to properly identify the difference b/t the different blocks within the building I saved.

Actual behaviour

The builder is asking for the wrong materials.

Materials used: AE2 Dense Cable (Fluix), AE2 Covered Cable (Fluix), AE2 Covered Cable (Lime), AE2 Illuminated Panel, AE2 Quartz Fiber. Ender IO Dark Pressure Plate.

All of the AE2 items are listed as 'AE2 Cable and/or Bus' in the builder's 'Required Resources' tab and the Dark Pressure Plates are listed as Wooden Pressure Plates

The odd thing about the dark pressure (mistaken for Wooden) is that the request even shows a weird image and putting normal wooden pressure plates in the inventory of the builder hut and it's inventory does not get them to use them.

Want to back this issue? Post a bounty on it! We accept bounties via Bountysource.

Start by reproducing schematic creation and saving with the listed AE2 and Ender IO blocks, then trace the save tool's block-identification and required-resource handling. Done means each non-standard block is registered distinctly, the builder requests the correct materials, and those materials are accepted when supplied.
