Since this seems to be the current go-to place for errors with tracking, I'll add some of the ones I've been pushing since January to see if anything happens here (can't hurt!)

There are two FIFA games for Vita: FIFA Soccer and FIFA 13. All the North American sales for the title have been added to the first version, even sales that FIFA 13 made. Italo correctly spotted it 3 months ago yet FIFA 13 sales are still being added to FIFA Soccer.
Ninja Gaiden Sigma 2 Plus tracking:
According to NPD numbers for February it sold 3k. We have it at 0k. Track this game please, ioi!
Dead or Alive 5 Plus tracking:
Also completely untracked in North America, though we didn't get any numbers for it in March's NPD.
God of War: Ascension undertracked:

There's probably loads more that I could figure it, but it's 1AM and I'm tired, so maybe I'll add a few more tomorrow.
