"Lost balance, when ready press jump to stand up"

Both teams spawned into a match on Cliffside, but the score board was broken and nobody could perform any action besides moving, jumping, crouching and talking on the radio and through proximity. We could not equip any weapons. Across the screen was the message "lost balance, when ready press jump to stand up" accompanied by some sort of a scope icon on the HUD. Deciding to end it all, both teams threw themselves from the balcony into the desert but survived. Eventually everyone timed out. I should note that the Cliffside we voted on was at the top of the map list, and so was presumably the official map rather than a mod or something.
