I am having a problem starting the fusion reaction in the larger sizes. The two small reactors work. The two large ones just wont fire. I put on the launch pad a 3.75 m fusion reactor and generator, stacks and stacks of 2.5 m batteries, and three of the large black triangular radiators. The gen is set to solid state, but i have tried with two generators, one set to each mode also. I have tried smaller fission reactors and microwave power from fission power stations to start the reaction to no avail. I have many mods installed but i used the Mod Admin to install all of them. I feel like this is a bug or a broken install somewhere, but am I just missing something?
