Title says it all.
I’m playing in TVHM as Fragtrap, and moving all of the handles to show green to turn off the flow of effluent in Stanton’s Liver does nothing. I’ve quit and tried this again, in the same session with the same result.
This is a bug which I’ve never experienced before with other characters, and having played over 350+ hours in the game, so I wonder if anyone else has encountered this.
I have never seen that, though 6 characters all through TVHM and a few more past that mission in UVHM. If after a full restart it’s still like that, all I can suggest is posting in the relevant on-line play section to see if someone has it open in TVHM and can let you join their game.
If you’re on 360 I can look and see if one of my toons still has it available.
I’m pretty sure you need to turn all the levers red, since you’re supposed to be closing the pipe.
Use the middle and far right valve
@miles_wimbrow this, just completed it for the 12th time, all levers need to be RED, not GREEN
Oh my god, for realsies?
Well sheeyit…
For real real, not for play play.
This happened to me the last time I played it. I completely forgot.
Yep, I felt like a real idiot 
Sometimes playing this game is like going into autopilot, and sometimes the autopilot is wrong.
