My noob guess would be either Checkpoint, Loras, or Prompting. Wouldn't know about those lengthy descriptions you do, since I rather stick with tags. But from what I tested it works pretty well. Did 2 quick, rough gens with Hyphoria Real and had no issues (see below). So my guess would be on your checkpoint merge. But, again, noob guess.

@hillbilly987654321 Thanks for the quick response. I learned that the natural speech prompts in general produce more detailed results, and they come close to what I exprect way faster than using tags alone.
Quite possible that this interferes with your LoRA, though it'd be the first one I run across. I got a few good butterfly images, but each time the hands were mangled, so I didn't want to post them.

@Kerisable literally all sample images prove my point. There's not a single one where the girls do anything different than stand or sit (upright) with their legs spread.
