Backup your map source folder.
Fix all those red errors in launcher.

going over the structural brushes limit can cause error-1073
Select a few hundred brushes (minus walls floor and roof brushes.)
right click with the brushes selected and make "detail".
Caulk and clean up unused brushes.

Compile.
