Yesterday in a game of throw down, my team backed out in the lobby before the game started and left me to fend for my self against a team of 4 until new players joined in.

With the new red X I know you guys are listening so I hope you see this as well 
Here’s a video showing the issue for those of you who don’t know about it:
