This list is my shopping list of things to take a look for debugging, if something has been fixed but still bugged in vanilla you'll not find it here.

The ones I can do nothing about (to my knowledge):

- Prestige icon shown instead of dynasty in the top bar
- Learning from domain not taken account for piety / month
- Building modifier for the owner of the whole county
- The counter efficiency for MAA that is a nerf
- List sub-domain lease in the decision widget to revoke holy order
- tick_day console command

Confirmed:

- You can have more modifier than what the UI can display

- Loan are not really working as intended (be it from an holy order of a vassal from event) [Working on it]

- Creating the Mozarabic Head of Faith title consumes gold but doesn't create the title (does only seems to affect old saves) * need to know if people with this had FoI dlc

- AI spymaster sometimes cannot be removed for them (it's usually their mother)

- Genetic possessed / lunatic / depressed being overwrite by generic variant (instead of being revealed if your char had them)

- Mentor / Student not shown in relation tab UI (but does count in the number of relation)

- Claimant war a sometimes invalidate immediately (I've tested it, sometimes it will not be invalidated, sometimes will be, tryed to test a little bit with the code, but nothing changed, may not be able to be fixed)

To be tested:

- Sometimes you are not granted the house dynasty banner

- Char with court position can be hired as councillors but not the other way around

- Best Friend alliance event expiring instantly

=> https://forum.paradoxplaza.com/forum/threads/ck-iii-best-friend-alliance-event-expiring-instantly.1566392/

=> Cause & Fix found, will be included in next release

- IA now joigning in holy wars (can_defensively_join_holy_war & holy_war_defensive_join_value) Probably not a bug, just too many restrictions that give the impression it never work, I'll check the conditions to see if everything is right, if there is something wrong I'll change it. If the conditions are fine, probably make a new mod to be less restrictive.

- IA ignoring wartarget https://forum.paradoxplaza.com/forum/threads/ck-iii-ai-ignores-war-target.1547122/#post-28614222

QoL / Nice To have / Request:

- Add relations for Parent in-laws & Daughter and son in-law
- AI not being able to send marriage offers to the player (will be separated with a dedicated mod)
