I've been trying to figure out in what circumstances I would build a Social Matirx. Base is 10% research and 10% manufacture, and gives and gets adjacent bonus for research and manu.
I placed one inside / surrounded by 3 megafactories and my colony capital. I got +10% research and +70% manu when I expected +40% and +40%. When I mouse over, the tooltip says it is level 6 and +30% manu and +30% manu, instead of +30% manufacturing and +30% Research. Looks like the second boost isn't working right, both are applied to manufacturing, instead of one level bonus applied too research and one manufacturing.
