I use the "cleanup nodes" option after each node edit. After editing nodes positions, I hover over a node, right click and invoke the cleanup nodes command before I proceed with playing the track. That particular sequence of commands effectively prevents erratic behavior after editing for me. Without doing this, sometimes the track is silent or as you describe, the volume slider reacts erratically.
