TaskFollowNavMeshToCoord

Sometimes a path may not be able to be found. This could happen because there simply isn't any way to get there, or maybe a bunch of dynamic objects have blocked the way,
or maybe the destination is too far away. In this case the ped will simply stand still.
To identify when this has happened, you can use GET_NAVMESH_ROUTE_RESULT. This will help you find situations where peds cannot get to their target.

enum eNavScriptFlags {
    // Default flag

    // to be found, and will not slow down at the end of their route.

    // accompanying NAVDATA structure has the 'SlideToCoordHeading' member set correctly.
