Crash w/ Lord of the Rings Mod

[WenXin20]

Minecraft v1.15.2
Forge v31.2.45
Building Gadgets v3.4.0
Lord of the Rings v2.3

If a Copy-paste Gadget tries to place a schematic containing Drystone (crafted with 4 cobblestone) from the Lord of the Rings mod, the game will crash, most likely due to the connected textures the mod uses.

Looks to be a closed source mod and thus I can't debug it properly. Looks to be an incompatability issue, just avoid using those blocks. They seem to be doing some hacky things with the block rendering.
