The issue has been there a long time. Glad that i could help, if you call that help This is probably my favorite mod/addon ever. and now that it works i can finally blow up kerbin again fantastic work sir!
removing the version number on the folder fixes the issue!
i have been trying to figure out how to fix the mod for a long time so thank you
doing a quick google search on "north kerbin dynamics not working" doesn't show how to fix the explotions
