Builder Help

[Slinky_24]

Im having trouble with my builder blocks, not sure if Im doing something wrong because I haven't used them in a long time. I copied my house with landmarks and blueprints, put it in a builder with all my materials, and powered it with 5 steam engines. All I'm getting is this floating block that slowly moves around the build area. Plz help. Thanks

I think, that builder is disabled thanks to bugs.
