Land Unit AI Bug?

[bru888]

I am wondering if this fellow has uncovered something. Please take a look at these two attached test scenarios. In his "Unresponsive AI" thread, he said:

I have 1 Human British unit on a Primary VP with a British flag. I have 1 AI Japanese unit in its own zone 7 hexes away that I want to attack the single VP. It is Team 1. It does not move on test. Whether I tell it to Move to the VP Hex or Attack in general, it does neither. It is in supply and has Command points etc. Strangely, if ordered to move to a Hex that is not a VP or is unoccupied it DOES move.

I looked at it for a long time and tried many different iterations and I could not get that Japanese cavalry unit to do anything either. His scenario is contained in the file linked below called "test 6 - land" which I renamed only to differentiate it from the other file. Nothing else is changed about "test 6 - land" from what he uploaded.

The other file is named "test 6 - sea" and that's because I used his scenario and merely changed the terrain to sea, the two opposing units to ships, and the AI team task to Naval Capture Hex. The Japanese ship goes right for the hex on which the British ship is sitting, as commanded.

I thought the reason could be that there is a difference between the land task "Move to Hex" and the naval task "Naval Capture Hex" but the Japanese cavalry unit did not respond to "Seek & Destroy," either.

As you may know, I have been working on naval scenarios for quite a while now, for a reason. So, I would not have seen this Land Unit AI Bug if it does exist. Does it, do you think?

I don’t get it either with the AI logic sometimes. The AI can see through the fog of war to a degree, possibly only for some certain tasks.
If you move a unit away from a flag/supply point, the AI sometimes starts to move/capture or not.
In my MoveIt! scenario, the Move order works even with occupied hex.
If you move the MP unit away from London in test6-land, the cavalry also starts trotting.

We don't have to understand everything, do we?

I'm wondering, if maybe a single AI unit is not allowed to leave the only supply hex on the map if the player's unit could capture it sooner than the enemy's unit the players supply hex in return. If you put another cavalry unit with the same AI team on the test-6 map, everything works from the start.

EDIT: Don't know why Horst's scenario works, though....

Well, we have reported it and it's up to them to fix it. I hate to pile on their plate - they have much to address at this time because there seems to be an inordinate amount of bugs that were introduced or rehatched when they went to this 64-bit version - and the tournament is being held up accordingly. But that is part of my job as moderator here as I see it and I could not get that pair of horsies to move anywhere, not even one hex.

Maybe Bru's horses got too much beating, while my pirates are more eager to plunder!

So there is speculation that this might indeed be by design in that an AI unit will disobey orders and not leave a supply point for one reason or another? Shards' post in the forum member's thread seems to support this viewpoint. I leave it to the developers to determine whether this is a bug or not.
