Hi, I also have the same problem, any update on this?

“UATHelper: Packaging (Windows): LogInit: Display: LogWorldPartition: Error: Invalid partition grid ‘Layer_3’ referenced by actor cluster”

Ah looks like if you have a BSP in your map, then you can 't use Cull Volume.

I did manage to fix the issue even with BSP included with building the HLODs

How did you do this? I have no idea where this error is coming from. Its very odd.

First of all if you have Level actor in your level this can cause this issue as well, also BP_actors placed in the level cause this issue as well,
over all to find the actor that cause the error you can build HLOD manually that’s how I found the actors that causing the problem for me.
to do this after the crash you`ll have your HLOD folder with all the actors generated cluster actors:

  1. hide all the actors in your level using the eye icon.
  2. open the HLOD folder in your level and Pin all the actors so they become visible.
  3. now that you pin them down you have their detail panel accessible to manually build HLOD.
  4. select the actors that don’t have the HLOD built for them and “build HLOD” if this actor crash he got a problem.

if you have many HLOD actors you can select a bunch and then “Build HLOD”
then when its crash you found the actor that cause the error, thats how I fixed my level.
