I'm not sure if anyone has had any luck in adding new techs to the game so far. I thought I might try my hand at it. I've followed the basic modding guide in the sticky at the top and I've been able to see the tech item I've added. The only thing is that I can't consume it so that I can activate the tech later. I've mostly just copy/pasted another tech but changed the name around a bit so all the correct item tags should be there. I'm guessing there must be another config file which needs to point to the new tech. I don't suppose anyone might know where that is? Thanks!
