2 weeks ago This is just how the mod developer coded their feature's placement to be on the world surface. Obviously the world surface will only be the top most island. I changed all the vanilla ones programmatically to account for this. It is not something that can be done trivially to every feature for every mod and would need to be done individually on a mod by mod basis, on a feature by feature basis. This will not be fixed. Compatibility packs may be made if someone commissions it though.

Description
When playing with Aetherial Islands, you may notice some weird empty islands if they're placed below the island. Seems that datapack does not respect the vegetation for all layers, so the higher islands get trees, grass, structures, while the island that is spawned on lower Y values is missing everything except the grass blocks.
Expected Behaviour
You get your trees, grass and some other vegetation spawning as expected on these islands.
*Screenshot is taken when I tried to fix this myself, somewhat like this should happen. But my solution is somewhat crashy and not works with vanilla biomes.
Real Behaviour
You get empty islands with grass and stone, where the islands are generating below the another island.
Examples:
(↑ You can see the island above here, there are mostly no grass on the island below)
(↑ two screenshots of the same islands with different camera perspectives)
(↑ Biomes O' Plenty is very sensitive to this bug and you can reporduce the bug much easier with this mod installed)
(↑ The same screenshot with Night Vision effect)
Also to note, that there are also some weird occasions that the island turn to a flat cave biome related island due to the Y level, such as:
(the island could ignore that and have more smooth transition? I'm not sure that is possible due to worldgen limitations however)
The bug also happen with the cave biomes. Here you can see the issue properly. The same island have TWO separated biomes. The islands above are cave related ones, the one below is just a... Mushroom Island biome? But with the Sculk biome replaced the Mushroom Island biome. The another island below is just an ocean.
Conclusion and Solution
The bug is quite annoying and these random empty parts of the islands are pretty common, so I decided to report this here, because I believe that player could be able to have their vegetation spawned as expected. As a solution, you can try to populate the vegetation to all Y levels. The grass and tress may spawn in the cave biomes, but practically it may be more fun and rewarding solution, rather than just empty parts of the islands.
