I've never played DF before, so I don't know if htis is a bug or not. I just started Annot, and I have to turn all the flow switches on. Well, all of them turn on exacpt for one, which re-sets it self as soon as I get back.
U have to race to the room while its still flooded
Oh.... I was thinking that, but it looked like a bug. And besides, I wouldn't think that guy would swim through sewage just to get to his hideout. Think of the supply problems.
