Hello, I'm experiencing strange problem about Ascent Guidance. Autopilot status and PEG editor shows correct data and autopilot is engaging easily but no real control is provided by it, vessel fly straight up and turn upside down once hitting dense atmophsere. Any of ascent guidance mode work by the way, it happens in Stock-Style Gravity Turn and MJ Classic, too.
I'm playing KSP 1.3.1, using Mechjeb2 2.7.0.0 latest official release, 778 dev build doesn't help.
