Event dispatcher cannot be deleted, removed, or renamed after placing a period in the name. In the case of the example given, the editor will throw a warning "No Delegate found for NewEventDispatcher_0.hi" (note that the name is still shown with the ".hi" rather than the "_hi" that it was replaced with).

Steps to Reproduce
  1. Open the editor
  2. Create a new actor blueprint
  3. Add an Event Dispatcher
  4. Add ".hi" to the end of the name
  5. Press enter to confirm
  6. Rename the event dispatcher by replacing ".hi" with "_hi"
  7. Press enter to confirm

Result: The Event Dispatcher cannot be deleted, removed, or renamed
Expected: The Editor would throw an error when trying to place a period in the name of an Event Dispatcher
