Resolution Note:
Post from https://docs.unity3d.com/ScriptReference/Object.DestroyImmediate.html
This function should only be used when writing editor code since the delayed destruction will never be invoked in edit mode. In game code you should use Object.Destroy instead.
If the code should be executed in both edit- and playmode, you can use defines to change when you call which method.
