v2.7
Updated for v1.8.*. Various small inclusions of vanilla changes.

v2.6
Updated for Fate of Iberia v1.6. New mechanism to strip house claims from failed duel challengers added in, will prevent house claimants cycle challenging. Thanks to =Sarsante= for bringing the issue to my attention.

If a character possesses both a house and personal claim and loses a duel, the challenge is considered to have been made in the right of the personal claim, only the personal claim will be lost, and the house claim will be retained. When a character challenges with a house claim and does not possess a personal claim, then the challenge is considered to be made in the right of the house claim on behalf of the house, the loser will lose the house claim.

The same rules apply to a losing defender. If he possess a personal claim then only the personal claim will be lost and the house's claim, if it exists, will be retained. If the losing defender does not posses a personal claim, only a house claim, then the loss results in the loss of the house claim.

German loc update thanks to DarkMatter.

v2.5
German loc added thanks to Dillo.

v2.4.2
French loc update thanks to lexo1000.

v2.4.1
French loc update and fix thanks to lexo1000.

v2.4
Quick update for v1.5.1. Includes the new vanilla changes. Some of the mods ideas have been included into vanilla, as well as some additional artifact claims nerfs, but a lot haven't. Between the new vanilla changes and what the mod does the AI may be better domesticated and able to be trusted to be able to use the demand artifact interaction more often; the 15 year cooldown on AI evaluating the demand artifact interaction remains for now but I'll consider reducing it back to vanilla 5 years after more testing.

v2.3
Dynasty banners can only be gifted to the dynasty head, thanks to code from CirclePete.

v2.2
Fixes vanilla bug so you can now gift dynasty banners to the dynasty head. The AI can no longer gift artifacts to recipients that can not use the artifact, like dynasty banners to non-members of the banner's dynasty.

v2.1
If the AI character can not benefit from an artifact, the AI can no longer demand the artifact, declare an artifact claim war, challenge for the artifact, or scheme to steal the artifact. This will prevent the AI from doing silly things over dynasty banners for dynasties they don't belong to, and religious artifacts from other religions, that have accumulated house claims that have passed onto the AI character, but that the AI character can not benefit from if they possessed the artifact.

v2.0
Artifact claims war casus belli nerf now added. Artifact claim wars for house claims can not be pressed against members of the same dynasty; personal claims can still be pressed against dynasts. Additionally the AI can only declare artifact claim wars if the artifact is illustrious or famed tier, no more AI trinket wars; the player can still declare artifact claim wars for common and masterwork artifacts.
