Lighting not building. Swarm seems to be the cause

Ok, so I’d like to ask you to try something:

  1. Close all SwarmAgent.exe/SwarmCoordinator.exe instances.
  2. Backup SwarmInterface.dll and SwarmInterface.pdb (if it exists) in your Engine\Binaries\DotNET.
  3. Extract contents of attached file to Engine\Binaries\DotNET.
  4. Open up SwarmAgent.exe.
  5. Try to build lighting again.
  6. Copy log from SwarmAgent.exe and paste it here.

This will help me investigate as it is not happening here :(.

Thanks,
