I think the new update might have broken something... I can no longer use something like "class MyClass extends Layer" in my code. If I do, the device on the right goes black, and no errors are reported.
Also, if I open a file that was saved in a previous version of Framer (one in which I'm using classes) everything works right up until I hit save. If I save, then the screen on the right goes black.
The only workaround I've found is moving my code to a module, and then importing that module in my project. That means working on both Framer and SublimeText at the same time, which is OK, but my workflow was much faster by having everything in Framer (and once certain part of the code was ready, I moved that part to a module using SublimeText).
Is someone else having this issue or is it just me?
