about ancients, immortality chamber bug?

I've just uploaded a patch (1.0.28.1) which fixes an issue where entities weren't sleeping at the same time if they shared a house.

I'll look into the second issue you raise. They definitely should be fighting for you. It sounds like they might have the fight skill disabled or something. Though, it should always be active by default. In the morning I'll take a look, but you might be able to solve the issue temporarily by enabling that skill if it is indeed disabled.
