Diplomacy deeply flawed

[Jason2]

Last night, in my current game, I demanded Rock Colonization from the weakest race that bordered me. They responded that they would give the gift in the interest of peace but never did. I tried this five times and always received a positive response but never got the tech

I also asked several allies to declare war - they said they would and never did. In fact the treaty grid showed them in a trade alliance with the race they said they would go to war with!

Have these bugs been mentioned? The diplomacy model looks like it has depth - but not if it is only cosmetic without actually ever changing anything.
