When i try to safe my fury outfit with two two-handed axes, outfitter seems to save the whole outfit but when i change back to that outfit, the offhand weapon is missing and instead of the checkmark the questionmark is shown. Screenshots from the process are attached.

I am having the same issue.

Just hit "Rebuild For..." again, it'll "fix" it for now. That's all I do on my warrior.

Needs a better fix...
