Hey JT, I am using your utilities advanced industrial plots and the tech tree just shows all unknown icons. The last time this happened it was because I was using an older version of your addon pack. So not sure if this is a side effect of Kinggath updating SS. I can upgrade to the next building in the plan, but when I attempt to look at the tech tree it just shows all unknowns. The tech trees are working fine for buildings by other authors. Thanks, great mod.
