I'm getting frustrated cause the scientists keep leaving the table! I wish that collecting repeat collectables would add a few tech points. Cause it's taking way too long to earn enough to help them survive. I've actually restarted several times because memebers were dying before I could even choose a faction.
You don't get the extra tech points from children picking up repeat collectables until the child brings the collectable to the research table. Keep an eye on the Tech points at that point and you'll see an increase.
