[4.11 p5] Crash during blueprint compile

Hi,

I’m getting crash related to ClassGeneratedBy being null during blueprint compile. I see that you were tracking this situation (UE-11597 and UE-11595).

Steps to reproduce:

  1. Create Blueprint class derived from Actor class. Let call it BP_Actor.
  2. In BP_Actor create Custom Event with name TestEvent.
  3. Compile BP_Actor.
  4. Create Child Blueprint class derived from BP_Actor. Lets call it BP_Actor_Child.
  5. In BP_Actor_Child add call to TestEvent from BeginPlay event.
  6. In BP_Actor_Child create Custom Event with the same name as event created in parent class.
  7. Compile BP_Actor.
  8. Compile BP_Actor_Child and observe compilation error.
  9. Compile BP_Actor and observe crash.

Hello,

I have been able to reproduce the crash, and have entered a bug report (UE-26761). Thank you for your report, and for your clear repro steps.

Have a great day
