Thank you, I actually read about the upgrade minutes after I've posted this comment :D Looked weird to me that the mod mentioned the need for the specific upgrade only once in the segment that's pretty easy to skip accidently.
Hello. Thank you very much for the mod, I'm having a blast with S4P for the first time. But for some reason I can't assign anyone to be the researcher for the crystal. What exactly are the requirements? I've installed the mod just like in the instruction.
