When I instantiate a prefab with a NavMeshCut component on it (and with a Tile helper elsewhere in the scene, which took a while to realize was needed…):
Exception while updating graphs:
System.ArgumentException: CompareBaseObjectsInternal can only be called from the main thread.
Constructors and field initializers will be executed from the loading thread when loading a scene.
Don’t use this function in the constructor or field initializers, instead move initialization code to the Awake or Start function.
