TypeError: unsupported operand type(s) for +: 'NoneType' and 'Tensor'

Currently receiving this error on Img2Img. Not sure what is causing it per se, but this was used in conjunction with Multi-diffusion's noise inversion, and Dynamic CFG when the error occured.

Actually this seems to be a combination of different errors?
This might be hard to track down. Here are the other two I encountered. (I was able to trace it to Noise Inversion from Multi-Diffusion)

Just started to get this error in txt2img with Vladmandic's fork
Getting this error with inpainting model selected.

I'm also getting this error with inpainting models.
