Custom particles only load on some custom maps?

[AsheMosterMashe]

I have two different maps, the first one (door_light_test_map) seems to load all my custom particles, consistently, without issue.
But my second map (pickup_test2), (which is just the previous map with some junk removed and some textures swapped) will not load any of my particles and I don't know why.

This has been the case with various other custom maps too, sometimes they all load without issue despite a lot of red console text, while others fail to load the same number of custom particles or fewer.

Did you copy and rename your particle manifest to the new map? Custom particles need that to load.

Oh I'm an idiot, I didn't remember renaming it for the first map at all.
It's all working now, thanks!
