How much "pain" is this causing you?

Please explain the issue you experienced in the most condensed way possible
My liege changed during an independence war against Italy due to a Claimant faction winning their war. My war target did not change, so instead of fighting for independence against the new Liege, I was still fighting against the same character who was now a count. After winning the war less than a month later, I was gained independence from Italy.

Please explain how to reproduce the issue
1. Have a Claimant faction waging war on your Liege
2. Declare an Independence War against your Liege
3. Claimant Faction wins War
4. You are still at war with old Liege rather than the newly crowned Claimant

Is there anything else you think could help us identify/replicate the issue?
Not really, I feel like an Independence war should be against the Title that you are a vassal of rather than a character. If the title owner changes you should get the option to decide if you want to continue the war against the new holder as it works with some other types of wars.

Screenshots start after the Claimant faction took over, as this is an Ironman Game and that's how far back ending the process took me. (Thanks CK3 Twitter for that tip)

I have attached a save game

Okay, I recreated the bug. It is caused by being in an Independence faction, declaring a separate independence war before demands are pushed, and having your liege change while both you and the independence faction are at war with your liege. The Independence faction's war will end, but yours will not.

(DEBUG MODE REQUIRED FOR ADDING GOLD)
(KEEP THE GAME PAUSED)
1) 867 start date, start as count Rainier of Luxembourg (Vassal of Lotharingia)
2) Create Claimant Faction for King Ludwig II of East Francia for the Kingdom of Lotharingia
3) Immediately Press Demands
4) Use the debug console to add 10k gold to self. Recruit a ton of mercenaries for the sake of a quick war.
5) Switch Characters to Count Eudes of Besancon
6) Create an Independence Faction
7) Get to 500 Prestige (Call a hunt or just use debug mode)
(UNPAUSE THE GAME)
8) Declare an Independence War against your liege as soon as you have the prestige to do so (Do NOT press faction demands) <--- This is where the issue starts
9) You are now in an independence war vs your liege while also in a separate independence faction against your liege. Holland should have joined the faction by now.
10) Before the AI wins the liberty war, Holland will push the Independence Faction demands.
11) After the Liberty war ends, you will still be in an Independence war vs your previous liege who is now just a count.
12) Win the war and become independent. (You will probably want to just use the console to add gold to hire mercenaries to finish the war)
