Just for the record, I'm not getting any of these bugs, at all.
I got one weird immigrant who was named 'thief' but he started working as hard as anyone else. He still has a weird graphic that looks like a skeleton, but otherwise it's fine. Finding a spot to embark isn't hard at all, really. It's not as if lava isn't available everywhere, and thus just finding a nice balanced spot where mountains meet forest is about that is needed. Having a brook or river thrown is always nice too, but pretty easy to find and can be done without.
I love this update for dwarf mode, since my idiot dwarves actually sleep where they are supposed to, and setting up complex lever systems is much easier since the selection system isn't stuck one behind. Speaking as creator of complex water systems, I approve this all around. I haven't got any sieges yet, and I'm wondering if the goblins are having a problem or not, but that's all right now.
Guys, I don't mean to be difficult for people who are having problems, but this is really just ungrateful. We aren't paying a cent to play this game that even in alpha is amazing and fun. So yeah, tell the Toad about the bugs and problems so they can be fixed, but don't whine. All that does is leave a bad taste in everyone's mouth and probably makes toady less enthusiastic about DF as a whole. It also drives away newbies. I know when I'm deciding whether to play a game, the attitude of the veterans always affects my choice. Positive, helpful veterans are far more encouraging than angry resentful ones.
