After they added new categories for flags, I've wanted to add my own. I see the files titled "Flags", "FlagsOrganizations", and "FlagsAgency" and I can add/remove flags from there. But how do I add, remove, or rename the categories?
Every time I try to load KSP since 1.9.1, it gets stuck on "Verifying Expansion: Breaking Ground SquadExpansion/Serenity". I've tried waiting and reinstalling KSP but nothing seems to fix the problem.
