EXTREMELY ANTICLIMACTIC UPDATE!!!!!!!!!!!!
I started construction of the pumps and found out that you can't simply lay down the orders for a whole stack of pumps. Oh no, that would be too
easy. In order to transfer power all the pumps have to be built hanging, and so you can't lay down a new order until you have an order below it. That's fine. But the OTHER restriction I discovered is that the pumps have to actually be BUILT from the bottom up. I'm not exactly sure what happened but I ordered 20 pumps to be built, and a group of 8 of them built at the bottom (that was nice), and then there were some separated groups of 3 pumps further up the column. Later when I checked back, I saw ONLY the 8 pumps at the bottom, and a bunch of randomly scattered components where ostensibly functional pumps used to be.
My guess is that pumps can be "supported" by a construction ORDER, but not an active construction SITE, so when you start work building on the pump below an already completed one, the one above it deconstructs. That's my guess, since I haven't SEEN it happen.
So I'm facing the prospect of a horribly long construction time if I have to check back every 5 minutes to see if the next layer in the stack is ready to for construction to begin. While I'm waiting for this, I decide it's time I got around to building myself a Gladitorial Arena to make use of my various prisoners. When I'm digging out a channel in preparation to build a "one-way gate" (pressure plate + floor hatch) so my dwarves can easily walk in but prisoners can't get out, I get the one message I NEVER expected to see:
Digging designation cancelled: wet stone located.
So here's my question: Do I laugh now or do I cry?
