I'm trying to create a dynamic global blackboard in NodeCanvas. The flow I was looking for is having a blackboard spawned at runtime and all agents (placed on scene or dynamically spawned) subscribe to it. I already found out, that the way to make it work would be to spawn the blackboard first and the agents later. In case of "on scene" agents activating them after the blackboard is spawned also works. The other case I'm still missing is how to place already active agents and make them update the references to blackboard after it is spawned. Is there some particular method for that?
