If you leave Camille's range as she ults you, her ult should get canceled.
She shouldn't get a free extra 800 range dash on her ult to follow your dash because the moment your character takes to dash puts them in max range of her ult.
The 'no exit' area was not yet established, the area would get established in a place that I was not. OR the area would get established around me, and then eliminated because Camille is not in it...
