I'd like to start by saying this isn't an issue of not knowing how to save characters with custom backgrounds, hairs, etc. I understand the pathing system. For some reason the loader is asking me the location of a custom hair style generically named 'Hair.png' in the mods folder. I didn't apply this style. In fact i'm using the standard Samus hair. This is very irritating. I have to save my characters using vanilla and import the character files to the loader right now. Check out the attached picture. Any information or assistance would be great. Thanks.
Read the saving guide: "The loader uses local folders to manage characters." This has been discussed many times, I should probably add a note in to the guide to explicitly state that built in saving is not supported.
