Well technically I have NO mods installed as I recently uninstalled all of the mods I had due to how much they slowed up my game. I HAD Kerbal Alarm Clock, Mechjeb, and Kerbal Engineer. There is a very real chance that I just uninstalled wrong. Next I'm going to try landing on the Mun with a tripod of engines, and I'm going to try landing a small ship on Kerbin with landing legs. If either of those explode, then I will probably just backup my important save files and let Steam uninstall and reinstall KSP to my computer. I'll post again if my spaceships still explode after that.
