Uh, that's odd. There aren't many duplicated files in XCF, other than some armor variations for those available to your regular agents and "special" ones. I do have some redundant files, but these are edits I did ingame to change things to my liking and stored for security reasons, in order to re-apply them later once a new version of XCF shows up. I guess I'll wait for the next version of your trainer and see what happens.
