I don't know if anyone else has noticed this problem but from the main WW site (not the forums) the last 12/3 chapters (everything after LOTR 1069) isn't showing up on the main page. I'm not sure about other sites because NU doesn't pick up QI premium novels or aggregator sites.
I belive links are added manualy. So it should just be that WW staff have not added them to NU, or a reader for that chase. The account walling should not be the reason.
We seem to be behind, yeah. We'll look into it. If you feel like helping out in the mean time, you can manually submit chapters here: https://www.novelupdates.com/add-release/
Ah. Just realized this was never marked resolved. Long story short, the RSS bot was down for a bit today. It was not just WuxiaWorld's releases that were affected; we were temporarily behind on quite a bit. The bot was brought back online and caught up with what it missed shortly after I replied here.
