[libil2cpp] The exception message is: System error.

Hey, i got this "[libil2cpp] The exception message is: System error." message (inside browser console) after adding a new System-class. All over sudden a perfectly running project was completely destroyed. And it took me hours to find out what the problem is, since I made a few other changes in the meantime and couldn't figure out which one caused the problem. And I never thought it's the line that comes inside the auto-generated OnUpdate() function:

throw new System.NotImplementedException();

So this is no bug-request or something like that. This post is only for other developers that get stuck at the same problem and also for my future me: This line does not only throw a simple exception in the browsers console! Get rid of it immediately!

To Project Tiny developers: I love Project Tiny and I will continue using it, but things like that are sometimes really making me smash my head against the wall.
