So here's the rub: I have a copy of the newest KSP update (1.1.2) and I put Mechjeb onto it. So far, worked like a charm. Fired it up today, and the takeoff works fine, but when it gets near it's apoapsis the craft does several things. 1: Creates the node for the maneuver. 2: Doesn't line up for the maneuver. 3: Spins out of control, like the wheel has just been allowed to go free. 4: Fails to throttle up. 5: Continues counting past the maneuver. 6: Hits the ground in what the scientists refer to as a "Gravity's poodle" move. I've tried this with every craft I made as well as the stock ones, and I get the same result. I've turned on RCS, played with corrective steering, all of it. I don't know why it just began to glitch out. Please help!
