Shortcoming in supporting throne vs liege

[Tempto]

A friend and I are playing as lords in the North, which is ruled by a lord paramount who is under the king of the Iron Throne. The Iron Throne decided to invade Braavos, and while the lord paramount of the North decided to remain neutral, my friend, lord of Karhold, elected to aid the Iron Throne. Taking this decision rendered Karhold independent, and shortly thereafter, the lord paramount of the North (who should technically still be his liege) declared war on him. This doesn't make much sense and I don't think it should be possible.

Essentially, by deciding to help the Iron Throne in a war that did not involve the independence of the North whatsoever, Karhold basically doomed themselves because it allowed the North (which, again, should technically still be their liege) attack them. At the very least, Karhold should have had the Iron Throne as their liege temporarily (even though this wouldn't have been ideal since the raising of troops wouldn't have been optional, it's still better than being outright independent though).

Are there any plans to improve this?

Sadly the AI unable to deal with the mega-war.

What CB did the North use?

The North pushed some old lady's claim on the high lordship of the Last Hearth (my friend was both lord of that and Karhold).

I was suspecting this was a limitation of some sort, but a simple solution would perhaps be to automatically create a truce between the liege and his subject when something like this happens?

This sounds like a bug, as it should not be possible to do. It is probably a problem with that particular CB. Do you have a save from the problem?

Unfortunately, I do not. However, the king was pushing some lady's claim on the Last Hearth. Additionally, I later continued the game in single player myself and found Moat Cailin siding with the Iron Throne (and the North stayed neutral) and the same thing happened - Moat Cailin became "independent" and the North declared a war on them. I believe it was a de jure CB this time, but I'm not sure. I might have a save of the Moat Cailin thing, and I'll upload it if I can find it.
