I don’t have an answer for this, but I’ve reached out to an engineer to see if they have any information to share.
Thanks. This is a known issue that we are currently working on. Related, we are also aware that the website API docs are out of date.
That " Commit" link is a dump of all fixes integrated into from the Dev-Framework stream, where the original fix was made (with changelist 3374925). If you’re looking for the specific affected file, it was /Engine/Source/Runtime/Engine/Private/LevelActor.cpp - “Don’t throw warning about missing world context for inactive worlds.”
Cheers
