Hey I've been using this mod on the new 0.25 career mode, and i've hit a problem, I loaded up the KSP interstellar tech tree when I started, but it seems to be blocking me from seeing or accessing the highest tiers (the stuff like fusion reactors and warp drive), which were the main reason I got the mod. I can see and access the majority of what is available (the Fission reactors, Plasma thrusters and so on) but not the last few research nodes. I have researched every node available but it is not showing the last few. Can anyone help me understand/fix the problem?
