Lighting build failed-Apparent Lightmass Crash

I started doing some more work on my TE-LittleSaturn map today and I'm unable to build lighting because it seems that the Swarm Agent or lightmass is crashing. I get the "Destructable Not Lightmapped" error on every StaticMeshDestructable and the same goes for pretty much every other object in the map. All I have aadded to the map since it worked last are about a dozen BSP shapes and maybe 20 static meshes so it's not like very much has changed.



I've done some troubleshooting by verifying the tool cache, deleting the shader cache and replacing the Dominant Directional Light but that didn't help.



Another thing that has me thinking is that the un-brewed file size for this map seems un-realistically high (370,000 KB) and I'm wondering if that might have something to do with my problems. The brewed file size is right around 200,000 KB and file size after deleting the shader cache is 103,000 KB.



I will add that since all the changes to the cooking/brewing system the map's file size has been a moving target for what seems like no reason whatsoever. I could build-all 4 or 5 times in a row and get a different file size every time.



I would attach the log file but it's too big. Please PM me if you would be willing to take a look at it, I'd appreciate another set of eyes on this.



Thanks,
