[GAMEPLAY] Disconnected / AFK Not Being Detected in Game

It has happened twice since the recent patch.

The first time an ally disconnected while in champion select after they locked in a champion. In chat it said they disconnected. Champion select never showed them connected. Once in game, I could not "/remake" as they weren't recognized as not connected. After 20 minutes and a surrender, the end game result did not show their name red as if it detected them AFK.

The second time, an ally had connected to the game and loaded through the login screen but remained AFK at the base. The game did not detect them being AFK and thus didn't flag the game as meeting the "/remake" requirements.

This has only happened since the recent patch. I don't have a video of the incident but I'd like to know if anyone else has noticed this issue.
