Additional information:

this does not sound like a BuildCraft issue, if you are playing sevtech ages please report to the pack author instead: https://github.com/Darkosto/SevTech-Ages/issues

otherwise please report to tinkers as they add the crafting station

Crafting station? I don't think buildcraft has a crafting station. What does it look like?
