Yeah, nothing happened. I ended up just reinstalling. It’s still happening, too. Now it shows that you’re on version 6, but it’s not automatically updating or offering the update in any way.
Edit: Okay, so, it seems like there’s some kind of distinction between versions and updates or something, because to actually get to the next version, I have click the cog next to the launch button, choose to manage the installed file, click “Switch to another version”, then choose the latest update. Notably, Corrupted Kingdoms does automatically update for me, and also offers older versions through the same menu. I don’t know enough about the app to know what’s different, though.
