The thing that is tricky though is that the changes in state are affected by the the state's own state regarding the state of the state change.

Put another way:

My writing this comment is changing the state of our universe. I'm writing it because I perceive the state change. If time is solely illusion then there would be no difference in the state between Tick #145 and Tick #146, but there is and it is this comment, which means that the universe (or at least our universe) is dependant on something that you all say doesn't exist.

I'm not saying you're all wrong, but it is a pretty surprising thing if it's true and modal realism is false.
