I was building the beginning of my Mun base: a life support vessel. I built pretty much everything I needed and tried to launch. The spacecraft is relatively big but I didn't see any lag so I believe it isn't my PC performance's fault. Anyway, I then noticed I forgot launch clamps and I needed to strengthen a mid-section. I went back to VAB and everything was OK. After adding these things I tried launching again - something strange happen. I saw the whole interface but everything else was black. I tried reverting to launch and I appeared at the LaunchPad. For some reason I went back to VAB and then tried exiting to space center. KSP asked me whether I want to save the craft. Obviously I pressed yes and then went back to VAB again. After trying to load the craft, all I got was a VERY early version of it. I tried using the "auto-saved ship" thing and I got back my craft but the thing is that it was broken. All the stages (the bar on the right, not the physical stages) were gone and when I tried launching, KSP said "Craft size unknown!" Mods which could've affected something: Universal Storage, Karbonite, TAC life support, KIS, KAS. My vessel doesn't contain other mods I did try restarting KSP. Didn't change anything Craft file: HERE
