Although ungodly NLT Media move in mysterious ways.
For people who update their games using the cracked installer I doubt that they pay attention to version numbers at all: version numbers are only really significant and therefore noticeable to those who update manually using archives. Sometimes when there is a bug in an update NLT Media deliver a correction to players via the updater and increment the next full update by one, ignoring the bug fix, other times by two recognizing the bug fix.
Why? You'd have to ask them that one.
Tip: If you use the cracked updater and are having an issue with your game use the updater to verify the installation; if new files get downloaded you've got yourself a bug fix and maybe your problem will be solved. Also if you use the cracked updater don't update your NW.js because the next time you update and your files get checked before downloading, once the updater discovers your NW.js is different than one expected it'll download some or all of the old NW.js to replace your new one possibly causing you difficulties depending what gets replaced and what doesn't. Your game could get screwed up. Basic rule: If it isn't broke don't fix it. Updating your NW.js only helps if you update your game manually using achieves when only game files in the www folder are involved.
