I am having the same problem as https://opsive.com/forum/index.php?...ut-braking-the-behavior-tree.2732/#post-13484 had as I was trying to refactor the namespace of actions. I managed to recover the tree by exporting the current behavior tree as a single asset and editing the JSON file. But how can I import the changed tree back to the gameobject? Or where I can locate the current tree's JSON file(bonded to the current gameobject's Behavior Tree component)?
