PCG Generation not working in "Standalone" mode

Hi all

I have a PCG volume set to generate and swap seeds when my map launches (done from the level blueprint). It works perfectly when I test it in the “Selected Viewport” mode.

Here is the blueprint code.

The problem is that when I launch in “Standalone” mode, my PCG never spawns (trees, rocks etc.)

Any fixes? My PCG Volume Component has the setting “Generation Trigger” set to “Generate on Demand”.

A very annoying issue since my whole PCG system works perfectly when testing in the normal viewport mode.
