Hello,
I'm sure you've noticed that most replays, maybe even your own, can simply not be viewed anymore after some time. This seems to be a bug in Steam's leaderboards.
However, I have finally found a workaround, which is incidentally a little more efficient as well.
This means that all replays can now be viewed again (apart from old ones that are outdated/invalidated).
Enjoy viewing those super cracked runs!
Cheers
Jan
