Subsequent runs produce worse/different results #45

I've found that if I run a ComfyUI workflow multiple times (everything the same except seed), every result after the first is worse and/or significantly different in style/etc. If I close ComfyUI, then regenerate the image that came 2nd (from original workflow), I get the desired quality and style back. Run again with another seed, and I lose that. It's like AutomaticCFG is mutating something about the model, and not restoring that mutation after the workflow is done, thus, when another image is generated, that mutation is applied on top of the previous mutation. Hopefully this makes sense.

I looked into PromptControl, and I noticed that there's an explicit "unpatching" step done there for the model. I don't see that being done in this. https://github.com/asagi4/comfyui-prompt-control/blob/master/prompt_control/utils.py#L139
