Goldenflame Dragon posted a short update to The Dark Unknown’s Facebook page yesterday, announcing a significant bit of progress made:

Bandit and monster world AI now pretty much works on the outdoor map. Working now on leashes (to prevent spiders from leaving Mirkwood, as it were) as that’s the last thing the monster AIs need; then the comparatively simple “animal” AI for creatures that don’t have points of interest to visit. Then I guess I’ll need to start thinking about actual combat AI.

He was also able to get leashes working soon after posting the above.
