The screen was just grey, with text saying "Game over". I refreshed the page, but then I was told that I could only enter once, and that I had to wait for the next round, even though I didn't have the chance to participate in this one:(

It was a bug that is now fixed. Everything worked fine in the recent match.

Thanks, I will give it another try;)

I aswell had the same problem...

fixed now

Thank you for the feedback...
