AI blatantly cheating with naval maneuvers.

[Wizzington]

AI can see two seazones, this is pretty much necessary since computers cannot 'guess' where your fleet might be.

This is also true for land units.

Only when you are trying to lure them into a trap.

I was under impression that AI has no fog of war at all, not only 2 sea zones.
If you have land army that is 2 provinces away from AI's army and you send reinforcement as soon as it attacks, it will abort the attack even though it shouldn't know there is reinforcing army 2 provinces away.. So, it basically sees the whole map but doesn't always act like it does.

The AI uses fog of war in most circumstances, for example they can't go hunting for armies deep in your territory because they don't know you're there. In some cases they ignore it because otherwise it'd be far, far too easy to exploit the computer's lack of ability to handle gaps in information.

No, the AI will spam actions based on the knowledge of forces marching on them from far away. I get what you're trying to say, that it only "sees" these stacks when being marched upon, but experienced players have used this to get it to "cheat" and lift sieges or combine stacks into attrition through the fog of war and cripple its siege progress, melt its own stacks, or lose because they or their ally got sieged first and suddenly one side is the player's vassal.

On sea, it's less abusable, but on land you can definitely make the AI screw itself over without the inconvenience of ever having to actually move.

That's a bug tho.

an ai programmer dev admitting the ai has a bug? I lol'd. Hope it gets fixed then.

I'm not in the business of denying bugs, only fixing them. Same goes for the rest of Paradox.
