[R107] Can not read property 1 of null

So I just removed a bunch of dead layouts, and now this error is popping up

I am not running any custom scripts or plugins, and the error occurs with both Firefox and Chrome

Please see how to report bugs. We usually cannot do anything at all without the affected .capx project.

Sorry about that, I thought I'd attached a link

For the time being Construct 2 requires you to have at least one instance of each object on a layout, like the first message says. We will eventually remove this limitation, but for now just create a dummy layout and drop a single instance of every object on to it.
