On that note: the popup "War Report: Resented Vassals" should probably read "War Report: Resentful Vassals"; the same popup is also missing a space character (" ") in the part "...or politicalinfluence, ..."

There is a small error in "Sabotage Attempts" popup:

"The more powerful people talks about you, the more..."
::"talks" should be the singular "talk" instead
"The more powerful people talk about you, the more..."

origin_disgracednoble trait has incorrect localization, where it's accompanying .yml entry is trait_origin_disgracednoble_noble (i.e. drop the extra "_noble" at the end)

random_war_malus_17:0 "Strategic failure" should be capitalized for both letters, i.e.
random_war_malus_17:0 "Strategic Failure"

oh i only see this now! Thanks for the contribution. These fixes will be in the next update.
