Is there a fix for WorldSettings_1 insistance on the lighting being rebuilt?

Everytime I light my map, save, then reload, the map checker states, “WorldSettings_1: Map needs lighting rebuilt.”

When I light the map again, then run the checker, it doesn’t appear. But if I should save and reload the map, it will come back.

I tried copy and pasting the contents of the level into a new level and relighting, but the same issue occurs. Help!

Hey QT,

To see what is throwing the error you can use the command DumpUnbuiltLightInteractions in the Output Log window and this will give you a print out of all the Actors that are not being built that causes lighting to be invalidated.

Once you know this it can be easier to troubleshoot your issue by seeing what is possibly happening with the offending actor(s).
