I figured out why I was so confused about games showing up!

When a 1-day boot time game is created (on Invention anyways, I'm assuming other games as well) it pops up in the top right and tells me a new realtime game has been started (with the lightning symbol and everything).

I would then go to the list of realtime games and notice it wasn't in the list of realtime games and complained about it.

The bug is not that I don't see real-time games, it's that games are being incorrectly reported as being real-time.  I have only directly observed this with games that have a 1-day boot timer.

Yup there was a bug there where games were misidentified as realtime - it should now be fixed, thanks Andernut.
