"zero uncond" vs "null uncond" with VPred SDXL

A dedicated workflow for my current vpred model, unfourtunately hitting a Math special case, causing drastic difference between WebUIs and ComfyUI.

It is likely occurs when you switch objective variable (e.g. eps to vpred, vpred to RF) from a finetuned model. It will eventually fade off (null uncond matches zero uncond) when more GPU hours are baked in.
