Yeah, agreed. It did nothing to correct any existing errors (except Itachi and Orochimaru I guess) and even added a few new ones like Yahiko's age and the worst of all, Tobirama dying only 31 years ago when the Sannin were already adults. It even considers all of the events of Part 1, including the battle with Haku to be "4 years ago" but Hiruzen's fight with the dead Hokage to be "5 years ago". I really hope we get a future guidebook with a comprehensive timeline (like Dragon Ball's Daizenshuu 7, for example), so this stuff can finally be put to rest.
