Can you elaborate a bit? I don't quite understand what you mean by 
changesets that have been missed. What exactly are you doing, and in 
what way do the results look wrong?

- Are you sure that we're all on the same page regarding the meaning of 
changeset columns in the database, especially that the "closed_at" date 
is only fixed once it is in the past - as long as "closed_at" is in the 
future, it can still move forward or backward in time. (I'm not even 
sure I am right on this one but I trust I'll be told by someone if not ;-)
