+- Fixed `opposite` → `opposites` keyword on allomantic strength traits
+- Fixed decision `picture` to use `reference` block syntax
+- Changed deprecated `beautiful` trait to `beauty_good_3` on characters

 - Game crash on load caused by `@#` comment prefix in mod files

 - Cultures not appearing in-game due to empty pillar definitions (heritage and language missing required `type`, `is_shown`, and `ai_will_do` fields)
