Howdy. Finally decided to give this mod a try. I downloaded it, and unzipped to a new DF40d11 installation. Poked around the raw files to make sure I wasn't missing anything. Half the raws were missing. Puzzled, I re-unzip. They are all back. I shrug, delete the extras, and gen a world. It keeps rejecting regions until it gives me the " We can't seem to place a controllable Civ. Do you wish to abort and check your settings?" dialog. I shrug again, having never really gotten this dialog before, and say okay, abort. I had upped the amount of volcanism, among other things, so I reset, select a large map instead of the medium one I was doing before, and try again. Again, I get the "not able to place controllable civ" box.
Still puzzled, I let it continue to try with these settings. After more rejections, I let it build a world that's Legends only. It's filled with orc towers, caves, and nothing else. I assume orcs are so awesome, they killed all the other races before worldgen could stop. I don't save the world for legend viewing, and mess with the orcs for a bit. After repeatedly failed worldgens, even using 'create a world now', I eventually save a Legend only world and start browsing through it. Finally, I found the problem.
Orcs were the only Civ being spawned. No dwarves, elves, humans, goblins or even kolbolds. I took another look at the raws.
The 'creature_standard' raw was a blank file. I think when the zipfile conked on me, it stopped before filling out creature_standard, and when I re-unzipped, I must have deleted the full one instead of the empty one, and hadn't caught it. So it knew there was a dwarven civilization, it just didn't know what a dwarf was.
Anyway, I hope it was just the zip program I used that weirded out, and not the file itself. I believe I downloaded it from the DFFD, but I honestly don't remember.
Now, to go have some orcish FUN!
