Stuff like this is always reparable with a bit of time and patience.
If you look in the mod's XML files you should see some sort of unique identifier for the various body parts. If you search your save file for those and carefully remove the NPCs—as well as references to those NPCs—that have those body parts (or change the removed parts to something that still exists in the game) it should correct the issue.
Just make sure to make a backup of your save first. The save format is pretty much just a dump of the game's internal structures, so it's a bit of a tangled web.
"A bit of a tangled web", right. I just attempted to remove one of the kobolds (which after removing the mod turned into otters with mouse limbs and dragon horns) and somehow disabled the UI on the left and right sides of the window, plus the combat UI.
I think I'll just export the character and start over, I hadn't even broken level 15 yet. Weird part is, of the two characters I used the mods with, just that one seems to be the worst off, even though I used the same mods the same amount on a second.
Fun tidbit: the otter I tried erasing glitched horribly somehow. It had no name and was unsellable, the game just kept giving me the critter's value. And that was
before trying to Thanos him.
Thanks for electing to help, but this honestly seems like it won't be worth the time spent for either of us. Or the headache.
SERIOUSLY, HOW DOES REMOVING A CHARACTER FUCK THE UI THAT MUCH
