i think theres been a oversight in the evolution of the lab, i go from eltromagnetism lab to elecrochemist lab which requires the previous version, then full spectrum atomics lab which requires the previous version, but heres wherei find it odd, the next generation, modules lab requires not the previous generation but the generation before it, aka the 2nd gen lab not the 3rd which would be more logical

modules lab is green/red science, so it does reuire green lab, not blue lab.
it is correct.

unless you have some other science, that alters it to higher tier, modules are tier 2 technology, not tier 3

it was this way all time
modules lab - tier 2
alien lab - tier 3

oh yea, my bad, modules lab is a offshoot lab just for the speed things :)
