If I may suggest something for you to work on, getting corrals to function the way they're designed to would be great. Currently they merely train sheep which can be slaughtered for food. This isn't very useful, and only a few players use them in competitive games. Perhaps someone can point you to a more detailed description, but they are designed to work by garrisoning sheep (or other animals) in them, which will generate a slow trickle of food. This should be relatively easy to implement, and is sorely needed. If you have any questions on the code, feel free to ask in #0ad-dev on quakenet. Usually someone is around who can help you, and if they aren't, most of the programmers here read the logs and so can get back to you at a later time.
