While I admit that it's possible (and even fairly simple) to provide an in-universe explanation that doesn't change canon, it still leaves me on edge. Boba remained 'hidden' for four years (iirc) after he was presumed dead-by-Carkoon. The article says "For years it remained hidden away" (with these years being ones where Boba is still considered dead). The "years" it remained hidden could simply be some time span within those 4 years, but still, l personally get the impression that a longer time is implied. I feel that, canon-unchanged, the way the books 'explanation' is worded seems very odd. Of course, I've been quite paranoid and on-edge about possible canon changes ever since the new movies were announced, so I may just be being unreasonable and over-reactionary.
