tracing an InvalidOperationException
I am getting the error below and can not identify what is causing it. I can not consistently get the error to occur. It is most frequent when I load the project. It pops up infrequently during dev and Editor Play. Aside form System.Collection there is not a single reference to anything in my scripts in the error message. Any tips on how to trace/debug/other it?
