I'm getting this following exception. I have a GUITexture with an attached state machine. When on mouse down it goes to a new state which loads a new level, destroying everything on the current level. Then I get this exception in the console screen. I have this counter object in the new level that basically waits for 5 seconds and then loads the previous level. If I disable the DrawStateLabels option on the PlayMakerGUI in the new level then this exception does not happen. Can someone explain what are the assumptions that PlayMakerGUI make about the scene?
