These VFS errors appear for everyone, regardless of whether you got the Mirage or not. I always had them with DCS. Nothing to worry about.
However, this caught my attention:
00010.997 INFO WorldPlugIns: No 'registryPath' for 'VEAO_HAWK'
00014.461 INFO WorldPlugIns: No 'registryPath' for 'RAZBAM_M-2000C'
00015.873 INFO WorldPlugIns: No 'registryPath' for 'MIG-21BIS'You might want to try uninstalling the Mirage and reinstalling it again using either the module manager or DCS updater.
