Not per se a fail...but quite annoying: I wanted to expand my Mun Base. Science lab was already set up, so I build a complicated "Three-in-one" Landerstage, wich was basicly three landerprobes stacked on top of each other. One with Goo Container, one with the Science Jr. Mat. Bay, and on top Bob in his capsule comanding the whole monster. The goal was to carefully touch done the lowermost (goo) stage, decouple it, fly a couple of meters left or right, touch done again, decouple science Jr., fly a couple of meter and land Bob.... It worked out quite great...except the probes with the Science Jr./Goo did not have probe cores...and the thor landing legs on bobs lander didn't work and he tipped over -.- Soooo, I perfectly landed two pieces of space debris and a tipped lander at my Mun Base...You wont do any science today...
