Epic Meepo
Hero
Oof! Copy-and-paste isn't a great way to advance a timeline.Except they are, the entry still refers to Hero, its that they just copied the SCAG and didn't do any research.
Another example is Skuld. Calling it the longest continually occupied human city in Faerûn is taken straight from previous editions. Except it was in ruins in 4e, or at least part of it was. And that wasn't retconned, but because the Sundering and Abeir still get mentioned in the book.
Face it, its just sloppy research, nothing more.
