By the way, what happens when a tech has 2 or more prerequisites? Do you actually have wild lines going all over the place, or does it just branch from the first one?

running wild....for now, and it branches from the first one.
If there then comes a tech which also leads the a tech already "added" to the tree, a line will be drawn between those two techs also, no matter their placement.
Good point btw, i forgot about that one.
