Hello :-),
I'm experiencing issue with Lich army replenishment - Has this been addressed in a patch already or shall I wait?
Playing on PC, 1.0.4d patch (waiting for 1.0.5 on GOG). I transitioned from Chapter II to Chapter III on 1.0.2g patch. There have been no respecs at all. I picked Lich straight away, received 600 Zombies and Skeletons and: - If I kill a demon army with my that contains these zombies or skeletons (no matter the size, I even split them to 300-per-stack). I don't receive any new Zombies/Skeletons when I win a fight. - If I kill a demon army without Zombies/Skeletons, I receive new ones after a fight (got 14 Skeletons as a separate army when the fight happened).
This bug has been fixed in like 1.0.3, and you should have even received the undead retroactively. It's really odd you're still experiencing it. Are you sure you have the latest version, and did you check the integrity of game files?
