[CRASH] Everyone Disconnected, opposing team Reconnected and won (RANKED)

I attached a screen shot to show we were all Disconnected. As soon as I was able to reconnect I watched them destroy our nexus and end the game. I don't know if it was something with the server, but regardless I non-stop tried to reconnect and wasn't able to. This is extremely frustrating because it was promos for me and I only have a couple of hours to get out of Bronze hell and this is not helping. Has anyone experienced this recently or in the past 30 min ? I am posting this here to hopefully have it resolved and revoked from my promos. Looks like i'll be playing norm's until then. This is ridiculous.
