i noticed that the L-SET Thukker Advanced Component Manufacturing Efficiency rig does not give any bonus, at least for actual T2, T2 capital or tools BPs.
if you look at the attributes tab, it says “Thukker Enhanced Capital Component Material Reduction Bonus”, which is identical to the attribute in the L-SET Thukker Basic Capital Component rig.
i suspect the code was copied over from one to the other, but the modifications were not completed to make it apply to T2 components.
same issue exists for the M-SET rigs.
i have opened a bug report, but, maybe if more people report it, they will fix it sooner.
