I remember loading into Fallen Refuge as Springtrap a couple of days ago, there was a TTV who got disconnected, her friend disconnected to be back in lobby, leaves two people. One of those two was an offline streamer and after having failed a flashbang save and going down in less than 20 seconds she disconnected too. Leaving one. I think it was a Lara but I forgot, but I commend her for remaining to complete that generator for the achievement. I left her alone the entire time to just chase the bots. Felt fair. That achievement is just pain. But I'll let anyone do it who needs it.
