Other mistake: It's raining when Nameless and Sky are fighting (rain is dripping off their swords and is on Nameless' face when going towards Sky in slo-mo), but their entire bodies never get wet.

Continuity mistake: In the third rendition of the story of what happened at Zhao, Nameless shows that his attack could have immense precision by throwing all the additional sticks in the air along with the white one. Not only does the white stick change trajectory during the scene changes, but at the end the additional sticks all seem to fly in from a barrel just out of sight instead of falling all around Nameless' sword.
Nameless: Great calligraphy.
Broken Sword: Great swordsmanship.
Nameless: You didn't see my swordsmanship.
Broken Sword: Without it, I couldn't have written this calligraphy.
Question: In the final fight between Flying Snow and Broken Sword, how did they get their weapons back? Weren't their swords still in the palace?
Answer: Those were two different swords they had at the end. You can tell because when Broken Sword's weapon hits the sand when he drops it, you can clearly see the tapered point, not a broken edge.
