Umm, y'know farms need soil right? Do I need to water them at all? If so, are buckets used, or should I move the river (Which will have certain results, I excpect.)?
Kind of tricky. In 40d, underground farms just needed underground soil or irrigated cavern to grow. In 30.12 (Latest version I've reasonably played) underground farms need to be irrigated before any crop growth can start. You can designate it as a pond, which I've never done, or my usual tactic is to prepare to drain a murky pool into a good sized room by sealing it up with a flood gate already linked to a lever outside the room. In case the room ever unmuddies you can easily flood it again for the plots.
Be careful, if you're in a really rainy area, the pool might fill up faster than you can wall it off if you don't build all the flood controls beforehand.
Magma Mountain update:
7 hours of CPU time, still can't redraw the screen. The memory usage went up a staggering 8k, bringing the total from 1,752 megabytes to... 1,752 megabytes and 8k. I still hold out hope that it's computing steps, because it continues to react the same way as it did when I could still issue commands, and I can't think of whatever else would gradually freeze it up beyond an expanding loop. Unless it somehow goes infinite (And I'm banking on integer overflow here).
I'm almost tempted to say it's hit an infinite loop, but it went near 3 hours without a single error and I could still control the game to an extent, including issuing commands to dwarves that were obeyed. I think the magma pressure load just got too much and that's all it's crunching now. At this rate I probably won't have to worry about starvation until november, long as I can keep this computer from crashing.
Other forts update:
Decided to breach HFS on my fort of 90ish dwarves. I got bored with no one invading and figured everyone could do with a dose of the whole clown car of Fun.
