The title pretty much says it all I build the lighting, it builds to 100% and says complete, Mapcheck shows some errors then says it needs to be rebuilt.
I can rebuild but it just repeats. There are no errors during the build of the lighting, should there be?
When I play the level it says lighting needs to be rebuild (18 unbuilt objects)
I was following this grass tutorial: Grass Quick Start | Unreal Engine Documentation
