Hatch didn't open after 2nd last Survivor died
Title says it all really, I think it has something to do with the survivor getting disconnected as the game registered him as dead, making it pause for a second before counting him as dead. Not sure if you could recreate this bug. Video of Bug: https://clips.twitch.tv/VenomousTangiblePrariedogTinyFace-6sscG4FJZptnCKM2
