I'm getting this warning for a quest in CK.

;BEGIN FRAGMENT Fragment_8

Function Fragment_8()

;BEGIN CODE

;WARNING: Unable to load fragment source from function Fragment_8 in script QF_ELSpuzzle_031D137E

;Source NOT loaded

;END CODE

EndFunction

;END FRAGMENT

Thing is quest runs fine. How do I pinpoint the error and what is the error? Thanks.

It means the source file is missing/corrupt. I've had that happen even on empty stages though, strange.

Try to regenerate your fragment.
