Compiling a List of Problems

[DON3k]

In the Cistern room with the valves and the bridge hanging by the rusty chain, as you've noted, you can turn the valve at the end more than once. This allowed me to 'solve' this room.

I never figured out how to lower the bridge that is suspended by the rusty chain, therfore I never found that note, or turned that valve. But by going back and turning the last valve at the end of the room again, this triggered the 'end' event for the room. The organic tissue appeared, and I was able to flee the room and the flooded stairs in the main chamber were then cleared of water.

Because of this, and there never really being a drive to lower that bridge by necessity, I never did.

But if I returned to the valve room, it was free of red tissue afterward, and the water monster was not around. The voice was no longer in the water chamber, and I again looked around for a way to lower the bridge, gave up and then proceed through the rest of the game. The valve did not allow a third turn.

Through the remainder of the game, all the way to end, my quest log continued to list the item that I needed to find a way to lower the bridge.

It did not prevent me from finishing the game.
