Externally Referenced warning - what does it mean?
I am curious as to the cause of this error warning:
Warning P_cloud7 ParticleSystemComponent /Game/Maps/Game.Game:PersistentLevel.P_cloud7.ParticleSystemComponent0 : Externally referenced

it means that one of the oldest and most irritating bugs known to man has not been fixed. 1 close the project. 2 in finder or file manager open the "Unreal Projects" directory 3 rename the projects route folder (yourgame to yourgame1) 4 open the project in the editor 5 file, Save All 6 Close the editor 7 in finder or file manager open the "Unreal Projects" directory again 8 rename the projects route folder back again (yourgame1 to yourgame) no more externaly referenced warnings

Important note for anyone still experiencing this issue after trying all of the above: Try deleting your 'Saved' folder in your project files. This worked for me after the rename trick failed, likely because I copied my whole project from another computer, and then upgraded to a newer version.
Just putting this out there since whenever I googled the problem, this thread came up first.
