A Blueprint compiling error is gone after reopening editor

Hi, there :
We’ve encounter a weird blueprint bug on UE4.6. The situation is :

  1. One of our blueprint can’t be compiled.( as attachment “blueprint_error.jpg” )
  2. Save all and close editor.
  3. Open editor.
  4. The blueprint becomes ok.( as attachment “blueprint_ok.jpg” )

Hope this information is useful for you.
Best regards.

Hi ZenTechEntertainment,

Does the blueprint produce this compilation error often or was it once and then when re-opened it no longer appears at all?
