Yes, I suppose this is part of the “beta” aspect of the software. It’s a failure of the Particle libraries themselves. I’ve reported it.
For what it’s worth, from my own diagnosis it appears to occur if the Game Frame loses its connection momentarily to the Wi-Fi router. When I moved it closer to my router, it appears to solve the issue. Mine has been rock-solid for weeks.
As a temporary workaround, I could add an automatic reboot at a certain time of day or after x hours. Does that sound useful?
