Please help, unable to cook with Niagara

After adding Niagara to our project, we can no longer generate Windows packages. Things I’ve tried so far:

  • Increasing Win32 path length > 260
  • Uninstalling/ReinstallingNIagara
  • Fixing Redirectors in /content folder

I can launch the game locally just fine, and I’m just trying to package for Win64 atm.

What I believe is the core error:

UATHelper: Cooking (Windows (64-bit)): LogWindows: Error: A dependency ‘NiagaraSystemEditorFolder /Game/Blueprints/Tower/Tower_C.Default__Tower_C_C:MuzzleFlash.NiagaraSystemEditorData_0.RootFolder’ of ‘Tower_C_C /Game/Levels/Level4_CombatActual.Level4_CombatActual:PersistentLevel.Tower_C_2’ was not actually in the linker tables and so will be ignored (2).

I can’t seem to find any reference to NiagaraSystemEditorFolder anywhere.
