It seems that if you try to connect multiple pools to something taking a pool as input, it just silently ignores one of the pools. I was wondering for a long time what was going wrong for a more complicated setup. I can't seem to be post a picture.
It would also be nice if I could see the numbers at each node to figure out where things are going wrong
If you hover over a node after a run it will show you the value at that node. Clicking the single run button is a good way to get to this quickly.
Sorry for the long delay in responding!
