I don’t have a solid Repro for this but I got pretty stumped by this.

I was working on a graph that gets a Frame Splits it and returns 3 frames.

And for some reason, the “Wall” output would only work, when both Lower Division was also connected to something.

for instance, this would not place the wall in the world

I could not make sense of it. Was there anything in my logic that was not working? I couldn’t spot it.

So wired a new output and deleted the old one, and when I did it suddenly started working. No other change in the logic.

Does sound like a bug, that sort of issue should be impossible, by design. If you ever get it again can you save and take a backup/zip of the procedure files and I can check through them for exactly what the inconsistency is. Also, does reloading fix it, and did you use undo at all?

It’s possible I used undo. If I hit it again I’ll try to get a better repro.
