Shifting value on null

[BlackVortexAI]

I love your highway nodes. It makes everything so much cleaner :) But what is very frustrating is if an output has no value due to e.g. a bypass, the values shift and e.g. the value of seed ends up at cfg output. This makes the error search a little complicated. A clear error message that a specific value is zero would be desirable here.

Hmm weird I thought that was being detected. Will take a look later when I have time.
