I haven’t really encountered this issue in my own setup, so I hadn’t paid much attention to it. However, it might occur when using complex prompts or combining this LoRA with other LoRAs. If you don’t want the hair ornament, try adding “no hair ornament” to your prompt. I might create an updated version that fixes this issue in the future, but I think someone more skilled than me will probably release another model before the anime airs. Sorry I couldn’t be of more help.
