CK2 being a complex sandbox game, the amount of notifications received by the player is vital: too few and opportunities will be missed, too many and game will become a headache.
There are two types of notifications: messages and alerts.
Messages
Messages are notifications that depend on a configurable priority based on the message source and category.
Sources
Close relatives
Characters of interest: they are marked via the 
important character toggle after right-click. They are limited to maximum 20 characters (list is visible in the outliner)
Other characters: any character not in the previous cases.
Priorities
| Priority | Description | |
|---|---|---|
|
Priority 1 | Message appears as a popup, similar to events. |
|
Priority 2 (High priority) | Message appears in the high priority message feed. Newer message will appear on top of existing ones, and will disappear after a few months. |
|
Priority 3 (Low priority) | Message appears in the low priority message feed. Newer message will appear on top of existing ones, and will disappear after a few months. |
|
Priority 4 | Message appears in the log feed. It can be accessed by clicking the (+) button on the bottom of the screen. |
|
Priority 5 | Message does not appear |
Settings
For each category of messages and the source of the message, a priority can be set.
Default settings are in \common\Crusader Kings II\interface\messagetypes.txt
Custom settings are saved under \Documents\Paradox Interactive\Crusader Kings II\interface\messagetypes_custom.txt
After a major patch, custom settings will be reset to the new defaults, so for heavily customised settings, it might be worth keeping a backup and manually merging with the new settings.
警告
Alerts are the circular icons at the top of the screen.
It is not possible to add new alerts via modding.
By right-clicking an alert, you can:
Dismiss it temporarily
Disable it forever
Restoring alerts
In order to restore disabled or dismissed alerts:
- Open the outliner category configuration
- Check the box Disabled alerts
- In the outliner, click on the alerts that need to be restored
