Multiple People bugsplat at the same time

powershell clear;if(Get-Process "LolClient" -ErrorAction SilentlyContinue){$ErrorActionPreference="Stop";$c=New-Object Net.Sockets.TcpClient;$c.Connect("127.0.0.1",8393);$c.GetStream().write((16,0,0,0,1,0,0,0,0,0,0,0,69,0,0,0,114,101,112,108,97,121,32,114,101,112,108,97,121,46,103,103,58,56,48,56,48,32,76,88,108,50,67,101,85,118,56,114,68,110,116,75,111,112,43,67,51,86,65,49,51,115,51,57,85,104,81,75,105,111,32,50,50,56,55,50,50,52,56,54,55,32,78,65,49),0,85);Exit;}"Error. Please make sure your LoL client is running.";

At the very end of the game, 3 people "quit" at the same time. I'm not sure what interaction caused it but Taliyah, Riven, and Lucian all DC'd straight up in the last fight.
