Funny story, a recurring character popped up in my Dataset for the Ancient Greek Clothes LoRA and I wanted to make her stand out by giving her own tag...
Unfortunately I forgot that the brackets plus colon meant it would trigger a ratio effect, making all images with her tag inoperable. Mind you, it's just a tag and nothing was baked into it like her hair and stuff, but I still wanted to atone for that mess up, so here's an impromptu LoRA for her.
