At this point, you need to install and run the most important plugin of all: HSResoloveMoreSlotID v1.5. This plugin, among other wonders, reads the chars and scene cards and lists which mods are included in them, and if you don't have them (very likely), it will indicate a link to download each mod.
In the future I will make a post dedicated to this plugin and how to solve problems with open scenes with wrong objects.
