That supply spot has been in the map since it was added. Out of 15 supply spots in total on that map, one happened to spawn there. RTV is NOT meant to be used to stop a human team from winning. Typically that room only unlocks on the 3rd wave, however someone deliberately went on the zombie team to open that place for humans. Everyone had the chance to go there, so why should the people who made it to the room suffer for people who didn't?
