sciences blue, purple, Green and yellow can only be crafted in assembling machines 3 to 6, even if the ingredient limitation is disabled in bob's assembling machines. I dont mind not being able to craft them in machines 1 and 2, but I cannot craft them in this mod's machines (https://mods.factorio.com/mod/MilesBobsExpansion) either

also, when I use FNEI with the sciences packs it tells me the ítem is unlocked in two different techs, one of them is not researchable, but the icon is not red, its tranparent

From your description it sounds, there is maybe some change in craft categories, i have nothad time for factorio for some time, so can’t give you eta for fix.

As for bobmilesextension it was never tested, there officially not supported.

As for fnei, fnei is wonky, and shows recipes from disabled research chains.

What about the blue science not being craftable as the requirement for crafting it (i.e. heavy and light oils from advanced oil processing) cant be made because advanced oil processing cant be researched as it requires the blue science pack. I have a picture for proof if you don't want to go look at it on your own. Great mod so far but have to disable it for now because of this.

There should be update for version 18 (i merged changes from trainwreck), to resolve this issue, for version 17 i plan to do it soon
