I have a normal moon lander with a normal launcher, I launched it, and before it got out of Kerbin's atmosphere the orbit on the map said I was going to escape Kerbin. I managed to do something and lower it enough so I could get a normal orbit around the moon, but the thing is, all of this was on my first stage. Normally, I would've been using my nuclear engines by now. I ignored it, and eventually was about to land on the moon before I had a chance to use my middle stage. So, I decoupled everything and started the landing process. When I was about to land, my moon lander went through the ground. I thrusted up and it went through the ground again, I tried to land again but the same thing happened. Eventually, I just gave up and let my moon lander drift through the mun's ground and then explode. I have no mods installed, either. Are you guys experiencing this as well?
