The patching steps just inject Oxide into the game - when you launched the game it should have made an oxide folder in the install folder. Download the mods from here and drop them into oxide/plugins: https://gitlab.com/underfelt/indie-nsfw-mods/-/tree/main/DungeonKeepHer/Mods
The BattleCameraFix mod won't prevent inhabitants from ending up stuck in court though. You can use CourtYeeter with it, it tracks everyone's position when going to court regardless of permission to be in court and warps everyone back to their last location regardless of if they were in court. But sometimes they were already stuck in court - if you have any stubbornly stuck inhabitants, with CourtYeeter, go to court and do shift+tab. In the debug/cheats menu there should be a new option "Dismiss everyone from court" that force-warps everyone back to the entrance of your dungeon
