If I use load image nodes stitch works as expected... when I try to stitch the image outputs of 2 different ksampler nodes (the "advanced" ones that have built-in VAE decode) it does not work, preview image shows nothing, nothing gets saved at the end.
Nevermind, sorry, it was a problem with an upstream node that wasn't stopping the generation but was flowing through the entire workflow and screwing everything up
