this crazy idea

I don’t know why it happened, but I can offer a solution:

If you’re on Firefox:

1. Open Javascript Console (press f12)
2. Click the button that looks like three rectangles in the top right and select the only other option
3. In the console, enter player.layers.intro.messages = 0

If you’re on Chrome (or 90% of other browsers):

1. Open Javascript Console (press f12)
2. Click the word “top” in the top left and set it to “index.html”
3. In the console, enter player.layers.intro.messages = 0
