Does the G-value influence the calculation of the structural integrity? If a broad structure on a G 1 planet just holds up, would it collapse on a 2 G or 3 G planet? Is the structural integrity calculated differently in multiplayer than in single player? I set a building in multiplayer that was completely okay and green after checking the SI. then I put another block (antenna) on top of such a section. The entire construction collapsed until the next support. The attached block should also have been dark green. What can that be? Thank you for useful information.
