[2020] Played ranked with my friends plugged in Ethernet upon return I got abandonment?

Hi there, @Pandax1115.

We aren't able to grant RP so it would be best to make sure you're plugged in before you start playing. If your connection changes mid-game, it's going to act as a disconnect. If you realize you didn't plug in your ethernet cable and are on wireless, wait until that match is done before plugging in.
