I'm a moderately-experienced player, I've made it as far as crash-landing on Vaythe with single-launch rockets, now I'm trying to dock for the first time so I can expand my horizons. But there's something really, really wrong with this particular rocket. I've already got the top half of my docking rocket (cockpit and landing unit) into orbit, now I'm trying to get the main fuel tank up there as well. But for some reason, this rocket will randomly stop responding to controls at varying points throughout its flight. Sometimes it will happen in the lower atmosphere just as the solid fuel boosters are about to expire, just now it happened as I was trying to migrate from a sub-orbital trajectory to a full orbit. The effects of this phenomenon vary. Sometimes the game won't let me activate stages or use the engines, but it will let me turn the aircraft. Other times, it will let me control the engines and progress through stages, but it won't let me turn. Now, I'm piloting this craft with two Stayputnik MK1s (Stayputniks so they can be detached and discarded after docking, two to counterbalance weight as one cannot be put on top of the docking port), and of course my first thought was that they ran out of power. But nope, they're each equipped with batteries and solar panels, and they were each at 100% power as my ship was spiraling out of control. Can someone explain to me why this is happening? Is it a bug? Pic related, it is the problematic craft. (Also unrelated question, but do adapters have fuel crossfeed? That small fuel tank on top is for smooth transitioning between the parts of the finished craft, but I'd like to know if it can feed into the orange tank or if it's just dead weight)
