My builder doesn't work. When i put template or blueprint into the builder and switch on energy the little cube starts to hover around.

But it doesn't build. Materials are inside.
Btw: Filler works fine.

Another problem is the library interface.

Maybe it will help: Blueprint, Blueprint library and architect table I can't find in normal creative inventory. I must cheat or use NEI to get them.

Builder was being worked on before 1.6.2 release, see https://github.com/BuildCraft/BuildCraft/tree/builder

I think people are trying to get 1.6.2 working right before cont. work on the builder, it was eating worlds like crazy before being removed.

Thx for answers.

Why wasn't builder removed, if it doesn't work anymore? And why is template craftable?

Because it's not going to be removed, it's just that noone has enough time to fix it. Also the template recipe was probably forgotten.

All I see is closed Errors. I assume when someone reports a bug they assume it will have a copy of it left open.

There is not bug.

Builder is disabled since 3.4.2.

says it all. Plus the builder can't be crafted or obtained in creative...
