Decided to continue work on one of my projects today and was unable to build the lighting.
I clicked “build lighting only” then got the “Lighting build failed.” error popup in the corner. The Message Log didn’t come up with anything, so I tried building the lighting on another level that already had the lighting built. I still got the same error. I opened swarm and looked at the logs tab
