Colored bricks from extra utilities turns white when used in carpenters (1.6.4)

I observed the behavior, and looking at the zip file it has a tile entity called TileEntityBlockColorData.class, so it's likely pulling info from there.

Blocks with tile entities are only partially supported as covers, and that's the reason these particular blocks don't have color.

I suppose there isn't any way to fix this.
Thanks for the quick response :)

The only way to resolve these types of issues is interpreting nbt tags on a per-block basis, which would be very time-consuming.
