Breaking Promises - Bug?

[Andy06r]

Here's the situation.

I promised the Incans my troop buildup was passing through (because it was - I was preparing to DoW the Dutch who was his neighbor).

China, my friend, asked me to attack the Incans. You don't accumulate warmonger with your friends in joint wars so I should sure!

Diplomacy Window looks like this

Dutch
Warmonger, Broke Promises, Covets my land, Denounced

Inca
Warmonger, you DoWed me, you have my capital (from an earlier war), backstabbed

China
Traded Recently, Friends, Common War, ... Broke Promises.

What the...?

Why is China mad at me for breaking my promise? They asked me too! If a joint war forgives warmonger, shouldn't it also forgive breaking the promise to not attack? Is this a bug?

Sure enough, once the DoF was up for renewal China refused it since the broken promise is such a big negative.

First of all, Inca and China are one of the deceptive civs so they probably wanted the easiest way to start hating on you.

Second of all, by breaking promises you show that you can't be trust and sadly this automatically marks you as such which is why "You've broken promises" is visible on ALL leaders.

Never promise not to attack unless you're not going to attack. Not even if a friend asks you to declare war on a mutual enemy, because it might be a trap. I once had a friend ask for a joint war against a mutual neighbor, and the very turn he's supposed to remind me, he declares war on ME instead. If I hadn't been autocracy-commerce-bigben, I wouldn't have been able to buy the Castle and 5 GWBombers that stopped his invasion of GWinfantry.

Breaking a promise is one of the worst atrocities you can do in the game. No civ seems to ever forgive you for it. Its not a bug, its to keep the player in check.

Yeah, it makes sense...if I know you're willing to screw over one person when I ask you to, I know you'll screw me over if someone else asks too.
