Careful, some spoilers…
After reading about this glitch on multiple forums, it seems this glitch is now being brought to Nintendo’s attention and they are acknowledging that indeed it is a bug.
There a game-breaking glitch that can occur during the Song of the Hero quest. It can halt your progress in the game and force you to start over.
Nintendo has responded to this complaint by isolating exactly what causes it to happen. Apparently the bug is triggered if you complete the Lanayru Desert portion of this quest first, then speak with Golo the Goron in Lanayru Mine, then complete the quest and receive that portion of the song, then go back to the mine and speak with Golo once more.
Doing all of these things locks the other two portions of the quest, preventing you from progressing in the game. Unless you have an earlier save file, this means having to start the adventure over. Considering this quest occurs rather late in the game, this is a tragic bug indeed for poor players who encounter it.
We’ve reached out to Nintendo to see if a patch will be released to fix this problem, we’ll update this story as we find out more. In the meantime, avoiding this issue is actually pretty easy. Just don’t talk to your Goron buddy more than once during that part. Or, even better, go for one of the other two portions of the quest first. Either of these will avoid the bug, but we certainly suggest just saving the Lanayru Desert mission for second or third. After all, it’s hard to pass up a lonely, chatty Goron.
I personally encountered a major glitch during a boss battle in Skyward Sword, I had to restart the Wii for it to fix itself and if I had not have saved recently that could have been very frustrating, have a look at the glitch and remember to save before you fight this battle.
The Legend of Zelda: Skyword Sword – Major Glitch (Spoilers)
When battling the boss (Abyssal Leviathan – “Tentalus”) after going after Nayru’s Flame on the Sandship I encountered a glitch.
What should happen is that Tentalus should knock the ship in such a way that the block falls down and Link can climb to the upper deck for the final moments of the battle.
When I captured this footage, that never happened. Essentially the game kicked into the final stages of the battle before moving to the top, which lead to a stalemate.
I believe this occurred because I kept using my Bow/Arrow to hit his eye when he fell instead of my sword.
I’m fortunate that I save a lot, so I had to reset the Wii and do it all over. If you did not save during the Sandship stage or prior… ouch.
Normal Boss Battle:
You’ll notice how the battle moves to the upper deck around 5:20 after using the sword.
