Tempus: Add warning about workingState equal to null
Created by: ccober6
It’s very easy to use the working state when one really should be using the current state, but the error message is an opaque segfault. Could we catch this in getWorkingState()? If it’s null just catch that ahead of time and say “Working state has been promoted (or other), it looks like you’ve called getWorkingState() where you should call getCurrentState()”? Something like that would be very helpful.
