Hi, for those still having trouble with an acting up LNAV:   If you are having one of those Mods installed, at least one of them is causing issues. I flew a departure out of UKOO (Odessa, RATN-1E)  twice with those mods loaded and VNAV was acting up, doing left /right turns and not catching up on the course. Next flight i tried without the "navigational" Mods and LNAV did a perfect departure, doing that "INTC" part just right.   So i recommend re-/moving these
