I'm working on a custom NPC, and ideally I want to do two things with her related to the beach bridge: 1) I don't want her to be accessible/meet-able until the bridge is repaired, 2) I would like to give her an introductory event that only unlocks after the bridge has been repaired. I've looked at the event modding resource (https://docs.google.com/spreadsheet...jYOMePaYe0Rc9BwQsj3h6sjyo/edit#gid=1007039997) and I'm prepared to dig through the XNB files if necessary, because I know there has to be something activated/switched on/etc when you repair the bridge, but I figured if anyone else already knew it would be quickest to ask first.
If you're using Content Patcher, you can check for the world state flag: Code: "When": { "HasFlag": "beachBridgeFixed" }
