Hello and thank you for your reply!

First of all thanks for the spacebar bug solution.
About Coroutines: I honestly didn’t realize they only work in play mode. I removed them and made a simple fix. I used them in first place because when OnValidate was called, node ID was 0, which caused problem with my implemented ID generation.

I still have one bug, that occurs when opening search window for nodes:
InvalidCastException: Cannot cast from source type to destination type.
UnityEditor.EditorGUILayout.BeginScrollView (Vector2 scrollPosition, Boolean alwaysShowHorizontal, Boolean alwaysShowVertical, UnityEngine.GUIStyle horizontalScrollbar, UnityEngine.GUIStyle verticalScrollbar, UnityEngine.GUIStyle background, UnityEngine.GUILayoutOption[] options) (at C:/buildslave/unity/build/Editor/Mono/EditorGUI.cs:7957)

Origin is class GenericMenuBrowser.cs line 345. This error occurs even if no nodes are in graph.

I figured it out!

I didn’t see node is type ActionNode. So I casted it into ActionNode and then took the action and casted it into I2Say, which is deriving from ActionTask:

ActionNode an = (ActionNode)node;
I2Say say = (I2Say)an.action;
say.RemoveTermReference();
