thewoodenlego Oh, I see. It's because you connected the plasma node pump to the straight way part which sends power two tiles away so the cross way part didn't receive any. The straight part is a one way part only.
I will add more T- and cross ways with different combination of distances (number of arrows = tiles skipped) for convenience.
Edit: Still won't work. I'll have to look into the code, although, I know it should work.
