Three days ago a developer I follow published an update, but neither the upload of the new files nor the devlog he published along with it showed up in my feed; I only noticed the update by looking through my mail, where there was the email notification. Past updates by the same developer showed up in my feed “correctly”, by the way.
The developer in question is “WOTB”, the game is “Tennis Ace” and the devlog is “Version 0.50 - Public Release”.
I think it may be a bug of some sort, the email even tagged it as a “Major Release” (like the past ones) so I don’t see why it shouldn’t show up in the feed.
[Edit: according to a post from phibbean, it was a problem with their publishing settings]
