Hi,
I´ve discoverd a bug in the Enigmatica 6 modpack where the distillation tower can´t be build. I guess it´s the steel scaffolding slab wich isn´t recogniced correctly. In the manual the mod doesn´t recognize the steel scaffolding slabs even thoug I had them in the Hotbar. I´ve double checked my configuration and the only possible issue is the slab. If this is not an issue with the mod itself, I´ve also contacted the support of the modpack.

You need the grated slabs now
