Onupgradeinga lair take a Tier 6 Consignment Shop. Notice it has tier 5 and 6 esource needs. So all but Tier one would be the same. SO starting at 1 you would deconstruct what you build take teh novians that you have from it and apply it to the next tier up. So it would partial be built and I belive you get Xp for applying Novians. No each time you starting at 2nd you will end up with novians that you can not use as there is no way to convert novians up to the next higer tier but it will still reduce youre work by some.
On craft machines I thought that their was only beginner journman and Expert for bonus to your skill. I am not sure how that will work for us. I wopuld assume that there is a new room that acts as a silo but does not look like a silo.
