There have been reports in recent days about a bug in The Legend of Zelda: Skyward Sword which can make it impossible to progress past a certain point in the game, potentially forcing players to have to start the whole thing from the beginning. As good as the game is, that would be no fun, so thankfully Nintendo have worked out what the problem is and sent an email out to players who contact them about it. It goes without saying that spoilers follow, but if you’re currently playing through Skyward Sword it might be worth at least skim reading to ensure that you don’t fall victim of the glitch yourself.
As reported by ZeldaInformer the email reads:
We have been made aware of the issue that results in being unable to progress in the Song of the Hero quest. If the game has been saved after completing the sequence of events, it will no longer be possible to proceed through the game on that save file. The only options at that point are to either start the game over or to use an earlier save file to continue.
The situation is caused by performing the following sequence of events during the Song of the Hero quest:
1. At the beginning of the quest, go to Lanayru Desert to retrieve the song of the Thunder Dragon.
2. In the Lanayru Mine, speak with Golo the Goron.
3. Complete the Thunder Dragon’s event, and receive his song.
4. Before heading to the forest or volcano regions, speak with Golo in the mine again.
5. At this point, the forest and volcano events will no longer occur, making it impossible to continue.
• This issue WILL NOT OCCUR if the Fire and Water Dragon songs have already been collected before collecting the Thunder Dragon’s song. Talking to Golo in the Lanayru Caves will also NOT trigger this issue.
• If the game has been saved after completing the sequence of events, it will no longer be possible to proceed through the game on that save file. The only options at that point are to either start the game over or to use an earlier save file to continue.
I wish I had a better answer, but I’m afraid there currently is no other fix available. I can assure, however, that we are documenting all feedback we receive on this issue. Thank you for your patience and support.
Sadly there’s no mention of a patch incoming, so for now this is the best we’ve got. But if you follow the above instructions you should be fine.
