[Client] Appearing offline and message issues

Played two games with my friend today and the first time he said he didn't see any of my (direct) messages or emotes while in game. After the game's conclusion, he said I appeared offline. I relogged and noticed the messages I had sent from lobby-end game lobby had deleted themselves and the last DMs to be listed were from an ARAM earlier in the day where he was not online. The second game was ARAM and my messages were showing at first, but somewhere near the end of the game or end game lobby, I appeared to be offline again and my messages and emotes where not sending/showing. In both cases, my entire friends list looked normal, including him. In between the SR and ARAM games, he said I was showing in lobby but the friends list showed me offline. After relogging, it went back to normal.
