What this is all about again?
How can there be so many people being in denial phase. If you want to claim something is a bug, with the lack of comments from higher powers, presenting a convincing proof is on you, and on you only. As funny as it sounds, we have to always assume anything that shows up on live server is working as intended, unless proven otherwise.
So what do we have here:
1.Misleading description theory.
Misleading description is not a proof of a bug. Misleading description is a misleading description.
2. Improvement theory.
New nano being superior to older nano is not a proof of a bug. New nano is superior to older nano because that's the whole point of making new nanos.
3. "Its coded differently" theory.
Differences between how particular coder achieves goal set by his bosses are not a proof of a bug.
Lets say i' m selling swiss cheese . This is like you coming back to my shop , yelling you want money back, because " hey, last one had holes on the other side".
What we have here is not a bug issue but a balance related issue.
Nothing to see here, move along.
