hi, i use this mod and have problem with "concrete base". i have mounted it on planet surface, with "x" or "h" button. i have built on it a floor and other objects. All is fine. THAN save - load, or exit to space centre, or exit to any scren AND BACK to building - causing unplug concrete base from surfase, all construction falling from first second after game have loaded. Or construction is hovering under surface and trying move on it makes kerbal "in flight" infinite state of being. Game version is latest 1.12. Addon version latest - 1.28. do u know about this bug? i can make screenshots if it help u to solve.
