Subscene has been working for a few months on the 3.0 version of their site, and this broke some of our links to their subtitles.
I didn't fix it sooner because it was very likely that Subscene was going to be changing drastically until the new version was stable, but I think enough time has passed now.
A few days ago I began to migrate to the new version and everything is going well so far. I've yet got to work to support the references of some old episodes, but the new ones are working well for the time being.
Subscene does a great job maintaing its subtitles catalog, make sure to say thanks by visiting every once in a while.
