I once had 2 witches meters apart on one of the staircases in no mercy hospital.
The funny thing is how it went:
I ran into the staircase.... and there was a witch ! So all shocked I bypass her by inches and run further up! AND THERE IS A WITCH, TOO !
So all shocked I somehow instantly crown her.... more like a reflext than intent. At the same time a teammate crowns the witch a bit further down. Dual witch crowning

Totally not intentional
