Hm, I think that might be a mod change forcing a recalculation of recipe unlocks, and Silicon Age does not come from technologies so it was missed. I will add a thing to re-enable recipes on mod list change when I get home.
I had to disable and re-enable the mod, than it works perfectly. Ive tested it with addong/removing Mods and researching Productivity from other mods. Everything works great now. Thank you Semenar, i like your mod
