And as Mills said
here, there's nothing more for them to say unless/until they can put a fix in a patch.
I guarantee you they have video evidence now as this has happened in Millennium's stream (twice in one game even) and I have a feeling he recorded it and sent it to the devs right after cutting stream if they needed more evidence.
