This only happens with Event Dispatchers which have an Input value. Without Input values it works as expected.
Steps to reproduce:
- Add an Event Dispatcher with an Input Value to your Blueprint
- Implement this event into some other Blueprint. Everything works as expected.
- Compile and save
- Restart the engine
- Open the Blueprint where the Event is implemented
- Blueprint gives compile error
- Click compile in BP (no changes done in BP)
- Compile error is gone
