I think this may have to do with the claw but I just spent hours building this planetary ship and now this happens whenever I try to do anything, Notice at the end where the long girder ship is flopping from the phantom forces of the other ship
Notice how this is happening during a ON-RAILS TIME ACCELERATION! I'm very annoyed Not to mention the claw is following the ship and rippling although it is detatched, this is the most messed up bug I have ever seen. This is without mods too. edit:looks like restarting the game fixed it although this was a very strange bug.
