>Also I found that some Loras have the char's tits hardcoded in really really strong and mess with the debreast lora.

It could have to do with size/shape also. I've noticed sagging breasts really want to "weld back" into place, for example.

Karras feeds noise, which can result in more unstable anatomy when your prompt is too loaded, but it might work better for this.

I'll give it a go when I'm home
