I am using UE4.12, and following this page https://docs.unrealengine.com/latest/INT/Engine/Blueprints/UserGuide/Types/LevelBlueprint/
At “To open a Level Blueprint for editing, click the Blueprints button in the Level Editor Toolbar and select Open Level Blueprint.”
I need to open level blueprint, but have problem finding the 'Blueprints" button. Where is it moved to in UE4.12?
