Autopilots not working

[volcanicshrimp]

When I try to launch a rocket into orbit using mechjeb it carries on going straight during the gravity turn and any other times when it should be turning. SAS also has the same problem. This happens most of the time but sometimes enabling navball guidance fixes it.

I use CKAN and the mods below.
