The Meta human knowledge for humans, as well as assigning them to human discount doesn't seem to be working. I assign all 8 of my Meta humans, but I don't get any more humans than I would have previously. The same is also true if I check my humans per ascension before and after getting the "Human Potential" upgrade. I think it might be additive rather than multiplicative like the description says.
Regardless of any superhuman limit, the humans I am getting are not going up, I am stuck at e11 humans, one upgrade of human potential should bring it up to e16, I think the upgrade was simply balanced to not be multiplicative, but the upgrade says multiplicative. I'm not getting any boost at all to my human production, and it's disappointing to see after I spent so much Meta Knowledge since it's not easy to get.
The new upgrade for the AI: Quark Duplication also doesn't seem to do anything. I have the upgrade, and 9.06e12 humans if I reset, but I then bought 6 million quark factories and still will only get 9.06e12 humans. I think something might just be going wrong with the Human calculation for all of these.
