This AI issue started with AOE3 DE.
In the original AOE3 the AI never goes Revolt.
Revolt is a bad strategy that ends the game prematurely.
Revolt should only be used when you are losing the game and you try to steal a victory in one last push.
Revolt should only be used in 1v1 games.
When I play 4v4 skirmish game with the AI 3-4 AI’s go Revolt for no good reason.
This basically kills the game because the AI has no economy left after that point.
Has this issue been resolved?
This issue is being tracked already. Thanks for the report!
That has been fixed 4 patches ago 
It had been resolved for treaty only, preventing AI to revolt during them.
If you are not playing treaty (or in smaller time treaty like 10-20 min), I don’t think IA is less prompt to revolt as before this patch.
If it weren’t for a treaty, I would have destroyed the opponent’s army and attacked the opponent’s town center in a normal game. I would be surprised if the AI has the chance to revolutionize.
This can also be fixed be creating a mod. I have crated a mod which seemed to work but i cant tested it deeply because of the game crashes.
You only have to rewrite a few rows in the ai script to prevent them from revolting.
After this patch i did not look after what changed in the ai script.
Maybe i can send you an example. But as i sad it is not well tested and thats why i did not published it yet.
