Occasionally, I will play a co-op vs AI match that never shows up in my match history in the client or on the website. This has so far only happened in Azir and Rek'sai games, is not clearly linked to time of day, first game of the day (either literally or for purposes of the bonus), or game length. I still receive IP and XP for the match, but it doesn't seem to be recorded anywhere else.
It's happened to me twice as well (one Caitlyn game and one Lux game). It mainly bothers me because of the Bilgewater event--the AI matches that are added are counting toward my assists, but the matches that aren't showing up on my match history also aren't having their assistes counted for the event.
With the first one, I got an "Attempting to Reconnect" toward the end, so I thought that may have had something to do with it. But there was nothing wrong with my Lux match, so I'm not sure what it is.
UPDATE: I guess it's actually delaying. The Caitlyn game is showing up, as is a Caitlyn ARAM game I was apparently missing.
