Solved Populating world with Custom Blocks that drop loot

I'm trying to populate my world with collectibles that drop unique items. The blocks are spawning and I'm saving their locations, but for some reason not all of the locations are being saved and I can't figure out why. It works perfectly until I reload or restart the server, then I have to reload it again for it to load the locations and some of the spawned blocks aren't saved into the locations.

Adding the Populator:


The Populator:


addCollectible():


Loading them from the file:


Saving them to the file:


In Collectible enum:

What does your config look like after saving the collectibles?

 

This continues for each type of collectible. When I stop and restart the server and teleport to a saved location, it doesn't drop the desired item. However, if I reload and then break it, it does. The plugin does load on startup which might affect that, but I can't really change that because that's how the populator works its magic.

 

@Zombie__Hunter
In that case my guess is as good as yours, it's probably just that the chunks in question aren't rendered at onEnable. Maybe there's some chunk loading magic that you can do to change that?

 

So the problem was that on startup the world is null. To fix it I made it load from the file using the WorldLoadEvent.
