I am having this problem as well... But it is a second bug that I uncovered while initially trying to figure out why Kerbal Space Program won't start (crashes with Oops! error) with WarpPlugin in my GameData folder, but starts up just fine if I remove it. When I try to start KSP with just the Interstellar mod and no other mods, that is when the game hangs up on loading the FNSmallerAugmentedArcjet
