There is confusion about an "Elephant DLC" module that apparently dropped with the first iteration of the patch - nobody is sure if this is an accidental leak or an inside joke or both. It could give credence to concerns about devs limiting mod access to skeletons so modders can't upstage paid DLC for elephants by just modding in their own - but so far the community is reacting with cautious optimism.

AFAIK, despite a number of official replies in the patch thread, nobody at TW has clarified the "Elephant DLC" situation.
WRONG! Callum made a somewhat vague statement saying it was an accidental release of experimental product.
