In template_reactions.json I only fixed conflict_bump2_reprimand_1 - I replaced "It seems like [actor_1]" with "It seems like [actor_0]"
For dialogues.json and random_events.json the game first loads original English files and then gets translated text by IDs, everything else is ignored. So you can ignore all changes in effects/requirements and all that other stuff, only actual text matters. I'm planning to make other files load like this too, so you won't have to worry about genres etc.
Btw you can use something like this to compare files from a new build and an old build https://www.diffnow.com/compare-clips You should probably backup JSON folder from each build just in case
