Coalition mechanics broken by war leader change?

[jusuff]

Playing as Spain I've declared war on Netherlands (trade dispute CB). Netherlands where part of coalition against be so the rest on coalition joined the war, including Austria, which became war leader. Then Austria called her allies, including Russia. Russia then became war leader. Nothing new so far.
But few months later Netherlands ask me for separate peace... I was little surprised so I've checked if I may also negotiate with them. I could. As I could with every other coalition member.

A few years later, history repeats, so I've decided to investigate this issue, declaring some wars on coalition members.
Each time coalition mechanics worked well (no separate peace) till someone outside coalition became war leader. This worked for trade dispute or conquest CB.

Is this bug? Maybe this is well know, but I haven't found such issue on forums before.

Edit: Found this playing 1.4.1.1 beta

Bump... Clarification would be appreciated.

Well from what I understand about coalition mechanics where you can never make separate peace with coalition members I think this is definitely a bug alright. I would definitely report it. I see that the new beta 1.4.1.2 is also out.
Maybe you could check whether this bug occurs there as well when you post the bug report. Nice catch by the way, seems to be a way to bypass coalitions.

Ok, thanks. Will check it in 1.4.1.2 and submit bug report if it still occurs.

You tell good jokes.

And what amused you in this sentence?

The assertion that coalition mechanics without separate peace as they stand can possibly work well of course.

Remember, with coalitions it can be set up so that you can't cede 16% war score's worth of land with 100% war score, and people can greatly obstruct progress without even being capable of contributing to the actual war at the cost of prestige at most...and the existence of no separate peace + no compensating factors for no separate peace is precisely the reason why coalitions are more like brake pads than meaningful military combinations in the majority of cases (IE it's usually easy to beat them, but you get less for doing so than beating a single nation ffs).

I decided to give you the benefit of the doubt and take it as a joke . Was that erroneous?
