So... anyone else found this place? There's two treasure chests, a radioactive chest with a hazmat symbol on it, and what looks like a vending machine. Can't open any of them and the game instantly forces you into crouch mode.

This is in North Sonora, literally inside the dome. I was minding my own business when the game suddenly spawned me there. Anyone else? o_O
