I tried that just now , and it didn’t work . I did it in a couple of different maps , I even got the copy I uploaded and put it into a new project (I assume thats what you did too) , I switched the light to movable , then back to stationary and rebuild , after that I tried to do it again just in case but this time I build lights with light set to movable then got it back to stationary and build again . The issue still persist , it is really a head scracher .
