Error if Draw Paths or NavMesh is active

[KWaldtParticipant]

Hello there!

RAIN AI is working fine so far (thank you for offering such a great asset!), however, I get errors if I have an AI-Object selected, which has “Draw Paths” enabled, or if I have selected the Navigation Mesh.
I’d still like to use “Draw Paths”, as it helps me debuging things, and I remember it working before.

This are errors I’m getting:

NullReferenceException: Object reference not set to an instance of an object
RAINEditor.Utility.Visualization.DrawNavMeshPathGraph (RAIN.Navigation.NavMesh.NavMeshPathGraph aGraph, Matrix4x4 aTransform, Color aColor, Single aOutlineColorOffset, Single aHeight)

RAINEditor.Navigation.NavMesh.NavMeshEditor.DrawGizmo (GizmoType aType, RAIN.Serialization.FieldWalker aWalker)

RAINEditor.TypeEditors.RAINTypeEditor:DrawFieldForGizmo(GizmoType, FieldWalker)
RAINEditor.Core.RAINComponentEditor:OnGizmoGUI(RAINComponent, GizmoType)
UnityEditor.DockArea:OnGUI()

Does anyone have an idea how to get around this?

Best Regards,
