Huh...I totally forgot about the Nemesis. I might have to finish that.
But yeah, loadouts have been buggy as hell for awhile. Sometimes you can't overright or delte them. Sometimes you can't even make new ones. The only way I've found to make it work is to change areas, swap weapons, sometimes fire a few times, and switch gear maybe. It's weird. But once you get it done it works fine. That's something.
