Simple bug/exploit to stop the payload from moving sombra puts a translocator under the payload and when the payload passes over it she warps into the payload and stops it from moving. Happened on the Rialto map where the payload has a large box on it she hid in there until one of my teammates killed her with Hanzos ultimate dragon strike.
Not sure if this is Rialto exclusive but that was the map where we couldn’t kill her besides with the ultimate that can travel through walls.
It was on PS4. The players name was “XMercy_MainX-maj” a report has already been filed against them.
