I am having an issue with what I think is load order of the built in C++ libraries. It might be that the Level Sequence Editor is loaded after editor utility actor and editor blutility classes
Setup: Create a new blueprint inheriting from Editor utility actor and add any of the Level Sequence Editor functions to the blueprint. They will function as expected
Save, close UE4, open UE4
You will should get the following warning:
Failed to load /Script/LevelSequenceEditor.Default__LevelSequenceEditorBlueprintLibrary Referenced by K2Node_CallFunction_4
and your blueprint nodes from the Level sequence editor library will show errors
Temporary Solution:
I have been fixing the problem by opening the blueprint to edit, file ->refresh all nodes. This functions well enough until the editor is closed and reopened again
Editor blutilities also exhibit this problem, but editor utility widgets do not for some reason
