Ksp Mun base flew away

[Locuz]

So i spend whole day to build my mun base but then few hours later i added some mods (near future and USI) then i went my game and it said something like this " Heavy transport lander lost cause pointy nosecone-b"

Can anyone explain that kerbal magic what wiped his wand and flew my mun base outer space and made that to debris?

Not I, but your thread has been moved to modded support in the hope that someone else recognizes this issue.
