When I want to watch a global replay I only get the loading animation.
Sometimes an error shows up in the console (“Failed to load 304580: undefined” at the startReplay function of game.js)
This occurs whenever I want to watch a replay since yesterday afternoon.
And by the way: why am I loosing ELO while winning most of the matches?
You can few the wiki page on the Elo system. If you beat a high Elo algo, you get more points than you would for beating a low Elo algo. If you beat a large number of low Elo algos, you will gain few points, but if you lose to a low Elo algo, you will lose a lot of points.
Ultimately, we have seen top algos rise to the top of the Elo system, and have a patch to further improve the system coming in this week. We are pretty happy with the Elo system, but will be investigating matchmaking.
They are working fine for me too.
