Help fixing a hero after removing a mod?

I've got a legacy hero who's supposed to have the Shadow theme and already has a shadow leg. Or had, I suppose. At some point I installed a mod that changed how themes work in the game, and it completely changed the Shadow theme altogether. Though I wasn't super happy with the way it looked, and eventually it became super outdated, so I finally got around to removing it... and now my poor hero is missing her leg completely. Is there any way to fix it?
