BAF Instance Crash

During a BAF Trial with a full premade League, within one minute of completing the entire league was disbanded, and sent back to RWZ, from which we had started the trial. The chat window claimed "You have quit your team," yet I sure didn't opt to do anything of the sort. This happened to every single member participating. Upon trying to rejoin, this error message appeared: "Error: Instance could not be found. It may have been completed or abandoned."

My in-game global is @Hemm I was the League leader. My logs should include every person that entered the league and everything that happened (that is reported via chat, at least) before the crash occurred.
