Hello, I have a problem with this mod: I've made a small mobile crane to move some module around. but when I dock my crane to a module, all the mechanical parts became bugged: impossible to move piston, hinges clip through the structure and explode, ect.. I tried to change/replace parts to both my movable modules and crane, removed every other mod, and nothing. every time I dock my rover-crane, the robotic parts totally bug. any idea? maybe another way to attach them instead of using docking ports? thanks in advance
