Rant: My AI art generator just started making the same face on every single person

I was using Stable Diffusion to make character portraits for a game last night, and after about 20 images, every new person had this same weird, slightly cross-eyed look. It didn't matter what I typed in the prompt. I tried changing the model, the sampler, and even restarted my whole setup, but it kept happening. Has anyone else's image AI gotten stuck in a loop like this recently? I'm worried the model I downloaded is broken.

Check your negative prompts. You might have accidentally set something that forces a specific facial expression.

Oh man, the whole "accidentally set something" thing hits way too close to home. I once spent like two hours trying to figure out why every face I generated had this weird, tight-lipped smile. Turns out I had "grinning" in my negative prompts because I was trying to avoid a different problem, and it just locked everyone into that same awkward expression. I swear my negative prompts are just a list of mistakes I've made before, it's honestly embarrassing how many times I've done that.

Wait, @anthony426, you can lock in a face just from a negative prompt? That's wild.
