It probably *is* a tribal vassal re-assigning himself. The problem is the UI presentation and timing of when the commander does so.
If I get another save with this I will submit it. I do not accept claims that UI and game-state being different can be WAD. That implies active dishonesty is WAD :/.
I had this same army with the same commanders selected when the AI attacked me. I'm well aware, because I save scummed this five times and started moving troops around to see if I could get different outcomes, and had a friend watching my steam broadcast as it happened.
This is flagrantly disingenuous. My complaint is expressly about the UI, not necessarily the mechanic. When the UI indicates one thing and the game does another, it's a bug. Even if the mechanic works perfectly.
It's the UI that's bugged. The UI. Continually discussing the mechanic rationale while ignoring the complaint (that the UI misrepresents it) is non-sequitur.
It's tiresome. EU 4 UI lies. HOI 4 UI lies. Even Civ 6 UI lies. This is not hyperbole.
When I show something like this:
And get told the mechanic is "WAD", the only thing it's a wad of is missing the point. I don't have much patience for this any more, because it pervades every Pdox title I've played. The above has been reported six times and completely ignored every single time. When it's a struggle to even get someone to address the complaint rather than quoting me and talking about something else, it's not a good start here either.
X = not X is not okay. Not in EU 4, not in HOI 4, not in CK 2.
- If the nation isn't going to be cobelligerent, don't lie and show me that it is.
- If the high chieftain isn't going to be a commander in the battle, don't show him as a commander immediately before the battle. If he auto-reassigns, give me indication that it happens before the fight. Representing a commander that won't fight the same as a commander that will fight within a day or two of a battle is degenerate.
