Uhm... something's off again on my side.
Are there specific symptoms I should be looking into?
It seems like this issue is back..?

Well it's fixed now.. so I didn't even get to clear cache and retry. But I did try opening on another browser (before writing my comment above) with similar results.
I want to be able to report a bug to the developers, but I have no idea what to tell them that might be useful. I guess I can dive into their issues tracker and take it from there.
