1. The Blade of Khorne, the in-battle ability from Khorne Roster that is given via a dilemma (Sacrifice 1,500 Khan's Horde + 8,000 gold for movement + ability) has a bar that cannot be filled in battle.

The UI text is "Bar Title"
"fill the bar by doing this"
"Points needed for next ability. 0/300"

Played a few Hung campaigns and it's the first time I encountered this dilemma and therefore the bug.

2. Ur-Khan has too many abilities after you unlock his Narrative Campaign rewards (Gates of Chaos Gods) that they don't all appear on the ability UI if you have all his unique line abilities + Masterful tactics from his redline. I'm not aware if you can adjust like you can do with Lords and heroes with multiple lores of magic. It's a great reward, though.

3. Dread Beasts of Mourn has too many entities. 2 or 3 I think would be perfectly fine, keeping it in-line with other "Tier 5" multiple entity units like Knights of Tor Gaval. Currently, they are without question the deadliest unit in the game. Hilariously fun, but greatly overtuned.

4. The Herald of the Raging Sky mission feels way too long to achieve. In a reasonably sweaty campaign I'm at 41 concurrent The Endless Steppes on turn 30. I think it should trigger on your Long Victory conditions, rather than a static turn 100. Even if you're an average player, you'll still be waiting around for 30 turns or so to reach turn 100. Or just trigger at 50 Steppes?
