Ok, who redid this quest to now require two people (or the use of a hireling)?

The gate "puzzle" had been straightforward, with the lever before the gate blocking the exit door acting to raise the gate behind you while lowering the gate in front of the exit door. Now suddenly that lever has no effect on the gate before the exit door, requiring the use of a hireling (or another person) to pull the middle lever in the outside hallway to open the gate in front of the exit door. You can no longer solo it without a hireling since the middle lever also raises the gate to block you from entering the corridor with the exit door.

I have never seen a post to the effect of "Hey Turbine, please redo your quests so we need at least one hireling to complete it solo."

I guess we have to get used to it, but I don't see the purpose.
