Hi! Firstly, thousand of thanks for your mod and the update, after trying a lot of different tech trees, this one was my favorite during .90 ! Though I have one little report to make if I may : Some nodes are empty. I know CTT is going through the same problem, and for people like me it's a bit troubling to pay science for nothing as a reward, is there any chances that this can be repaired? Anyway, I know from what I read that coding the tech tree is a brain killing puzzle, I was just wondering if there was any prospect for the empty nodes issue, or if I just have to try overcome this by ignoring it. Thanks again for your mod!
