If you have a flow or state machine running held in a wait it will cause Missing Reference Exceptions. Clicking the error highlights the CoRoutine Runner object.
To repproduce create 2 object, (happens with one aswell but you have to sam load the scene)
Create flow graphs on both , on one have On keyboard input triggering to load the scene.
On the other attach this flowgraph, which incidentally is another bug I believe, Ill post that one seperately, or maybe its just the cause of this one
When you run it wait 5 seconds or more and then hit Space to load scene, if it doesnt happen first time spam the key it will do it, then youll get this.
Initialy I had 2 scenes as I thought it was loading another scene that caused the roblem, but loading the same scene also caused it.
Also the more objects you have running state machines in a wait node the more errors youll get. I ran into it after Id modified the enemy AI with more waiting and then had level loading.
This is thread with wait bug, accidentaly put it in questions but couldnt edit it for some reason.
