What happened?

When generating a new world in the preview section biomes o' plenty biome do not display at all if the mod aromatic is installed. Aromatic is a world generation mod that adds cinnamon trees to vanilla jungles and to its own biome aromatic:cinnamon_rainforest.
The issue is resolved once the world is generated and previewed using the in-game preview.

After testing it seems that Aromatic does not seem to like the fake server we start up for the world preview, only working with the actual server once in-game. If you check under "Settings (wrench icon) -> Biomes" you can find the biome added by Aromatic.

Since the source code of Aromatic is not public, we cannot check what it is doing or why this is causing problems for the world preview, so this would sadly be marked as an incompatibility.

As to why it seems to affect the listing of Biomes o' plenty as well I'll investigate further.

Thank you for the in-depth reply, I've gotten in contact with the aromatic Devs to see if there's any chance it can become open source, until then thank you for your efforts!
