So I'm trying to make some progress on memory alpha, and I just crafted about 12 Large Hypos.
And then I realized that maybe you have to do something else, like craft one of each type of thing? And so on?
Do we have any definite answers on what you need/what you can craft in order to unlock the next scientist? Also, when you unlock them are you alerted to this fact or do you have to constantly check with the scientists to see if they like you yet?
