			1) I deleted all the Builtdata files (or I was gettting an error on save)

			2) Turn on "World Settings"->"Force No Precomputed Lighting"

			3) Build -> "Build LIghting only" (this will basically remove all the lightmaps in case you have any)

			4) Resave all.

			Since long time I was getting this error during relight: "InstancedFoliageActor_0 Large actor receives a pre-shadow and will cause an extreme performance hit unless bCastDynamicShadow is set to false."

			I changed Crystal_Light29 from Stationary to Static, and the error went away. We should not have stationary lights impacting landscape.

	In Unreal engine 5.x if you click on "Build All Levels" it will actually break the relight. The same if you click on "Build Geometry" as all the BP containing lights will disappear from the editor until you relaunch it. This causes the lights in BP not to be recalculated.
