If the user attempts to generate HLOD actors in a persistent level, when the sublevels have HLOD System disabled, they will receive the following warning:
The warning can be confusing because it doesn't make it clear that it's the sublevel, not the persistent level, that has HLOD disabled.
Multiple warnings will appear reading " WorldSettings Hierarchical LOD System is disabled, unable to build LOD actors", because sublevels have HLOD System disabled still.
Clear warnings indicated which level(s) have it disabled.
