I was in game, and we were in a fight when the "Attempting to Reconnect" thing came up. My internet was perfectly fine (I opened a browser to check.) I relaunch the client and the option to reconnect to the game was not there. Thinking that maybe the game had ended, I went to check my match history to check if my team had won, and the game was not there. I have no clue what just happened.

The server dumped the entire game slot itself, kicking everyone, erasing all history of the game. This wouldn't have been on your end, in this specific situation, it was completely server side.

Sorry about that.
