About diplo and vassals

[JujuLautre]

Answering to a new thread about diplo screwing up with vassals because the interface is misleading, I was wondering if this "solution" could be implemented: create a new diplomacy text which would say something like "we don't like your vassals/the people of your team", and appears when an AI refuses something because she is friendly with us but furious with our vassal.

Not sure it's what jdog or others would like to see this in the unofficial patch, but I thought I'd mention that.

Or perhaps in BUG ?
