Is the Maldraxxus Colliseum match bugged or was someone cheating?

I was just in a solo shuffle match at Maldraxxus where players were able to literally just walk around the guards and start on opposite team side. (I recorded 5/6 my match via obs so if i need to upload or give blizz a vid i can).

I was asking people in chat if someone was cheating or if the map was bugged.

If shuffle has come to people cheating now i don’t want it.

its bugged i just reported it also.

ya maldraxxus is bugged atm, any1 can walk through the gate on the sides

Yo im speccing spear RN

This is occurring on the proving grounds too. At least it was last night

I also randomly lost the last round. I waited for a 20 min queue to lose by a bug? What is this?
