Vermillion Problem

Just played Coop game on Vermillion Problem. Game started with missing voice line from Donny. He just stuck on my screen, say nothing and stare at me. Then map sound gone, later my partner announcer gone. At the end of the map we got 20/20 obj, but map didn’t end. After 1-2 min end sequence triggered, but then map totally froze and refuse to end. Only force close resolved this.
