As stated, the death dominion was restored to Dom2 levels, i.e. to where it should have been all along. It was an accidental oversight that led to the bug being introduced and as soon as KO noticed the problem in one of his own test games, it got whacked over the head with a weapon called Developer Keyboard, the Bane of Bugs.

The reason why it went so long unnoticed was probably people not paying enough attention to compare to Dom2. I know I've never played a single game with LA Ermor in Dom3. Played a few with Ashen Empire and Soul Gate in Dom2 and those killed the population off very, very fast.
