The last several books have been awesome, but there have been several apparent continuity errors, some minor, some glaring. For example, in Changes, Harry’s office moves to another floor. Someone somewhere said JB’s betas pointed this out to him, but it was left in intentionally by JB, that he told them it had to be this way for a reason. Why?!? What floor the office was on didn’t matter for the plot of the book, and it would have been an easy fix. This is admittedly an unimportant error, and something a lot of people wouldn't have noticed or cared about. Admittedly you could just shrug and assume his office moved at some point and wasn't mentioned. But why leave it in?!? Since there is a reason, that reason has to be important, and the reason sure wasn’t explained in Changes.
A far more major error is when everyone in SG agrees that Nicodemus was the original buyer for the shroud, and Marcone interfered. This is backwards. And repeated several times in SG, by both Harry and Anna Valmont. This is a HUGE error, imo. And not one the betas could possibly miss.
Let’s assume for the sake of argument this was a mistake by JB - how could that happen? JB has said he looks at wikipedia to find info on his prior books.
Per Wikipedia: “Dresden's onetime lover, Susan Rodriguez, escorts him to a high society art sales charity event run by Johnny Marcone, where the Shroud will likely be sold. The sale is
interrupted by the Denarians, who seize the Shroud and kidnap Dresden.” (Emphasis added)
So if JB followed his stated procedure, he would have realized Nicodemus was not the original buyer, and this error wouldn't have happened. So for this to be an error, JB would have ignored his stated procedure, and each and every beta missed a huge error. Seems highly unlikely.
So instead, I am betting this is evidence that things have been changed through - or because of - time travel. Thoughts?
