I left the documentation on the Blog.
First, you need to find out if it is a creature. Go to start game, gen a medium world with short history, then set everything else to Very Low. If it crashes try again. If it crashes again, then it might be something else, or more then one thing.
Second, Start a new world with the same thing above, except set 'Number of Beasts' to 'medium'. If it crashes, the problem is one of your creatures. Follow the steps below. If it doesn't crash, try again, and if it still doesn't then it might be something else.
1. Create two folders, Folder A and Folder B.
2. Take five creature_xxx files out of the raws, and put them into folder A. Then generate a new world. If the world crashes, take the files in Folder A and put them into Folder B. Repeat the process until the crashes stop.
3. Once you can successfully generate a world, you should have five text files in Folder A. One of them is causing the crash. Move one file back into the raws, and gen a new world. Repeat this process until it crashes. When it does crash, the last txt file you moved back has the bugged creature inside of it.
4. Make one text creature_xxx file for every creature in the culprit file. Put one creature in and gen a world, repeat this process until it crashes. Once it crashes, the creature you moved in last is the corrupted creature.
It takes a while.
But here's some stats from my creature. Perhaps you have a similar creature.
