Externally referenced warning (yes it's still here)

By default, leaving the maps list blank in the Mac side, it cooks all the maps in. On the Windows side, though, leaving it blank resulted in map load failure. The workaround for it was to manually list the maps to include in the package. Clearing and resetting the list broke it again. I don’t know if this is a result of the externally referenced bug or not since my entire project is plagued with the errors when I try to do a Windows build.
