It wasn't the accessing of the particular stage but accessing the 2012 Vuelta period from the initial link for that year. At the bottom of the Race & Results we have the link for the 2013 Vuelta and from there you have links to the previous years. Clicking on the link to
2012 Vuelta a Espana for some reason takes you to 2010 Vuelta instead. I was trying to figure exactly what stage from the 2012 Vuelta that Valverde crashed and lost time. I couldn't recall what position in the gc Valverde held before his crash and wanted to see for sure.
Edit: Thanks for looking into it.
