I’ve a fairly nasty bug that is affecting my work. It is possible to completely lose event graph in certain Blueprints, and once lost, it cannot be gotten back.
Reproduction steps:
Create a native subclass of UDamageType (Blueprintable, BlueprintType, MinimalAPI) - it needs no members.
Create a Blueprint of this new subclass.
Close event graph window.
event graph does not appear in My Blueprint tab. Closing editor without saving anything does not alleviate this issue, as this is now permanent for assets of this type. I have tried reparenting UDamageType to AActor, as well as removing const in UCLASS macro, and it has not solved anything.
This could put a serious dent in people’s workflow - so please help me get my event graph back!
As a side note - there’s a typo in UCLASS macro for UDamageType (UBlueprinable instead of UBlueprintable).

I hit this condition today in 4.11.1. I was able to fix it by closing all of other tabs (Construction Script, viewport, functions, etc.) and then closing and opening blueprint. It brought back Construction Script and Event Graph tabs when I reopened it. I had to go to “Window > Viewport” to then restore viewport tab.
