Hi.
Many errors, when you click on the they will highlight the object.
this might narrow down the issue.
also try turning of certain objects and see if there error still happens or not.
you could try edit the line 86 like this :
Debug.Log(e.Message + gameObject.GameObject.Name);
but i don't think this sends the out of range message. but you can at least try

you could also show the "reference" in the debug as well if it works and you have lots of arrays on the object
