I've been looking all over Fulgora, but I see no plants anywhere in the oil ocean. Maybe I'm wrong, but I think the map gen data is missing from the mod?

Hi UltraJohn, they do not spawn naturally, instead you find seeds hidden within the Fulgoran ruins. The lore is that they were being researched but the civilization collapsed before they could be propagated

Yeah I did find those seeds, but how am I supposed to unlock the research that requires me to mine the plant itself? I can't plant them before I mine one first lol. I might be misunderstanding it though, but the agriculture tower/research is locked behind the plant, not the seed.

Some of the ruins should have charged seeds, which you can plant manually to then get coralmium and progress through the research

Ahhh, gotcha. Yeah I didn't think of that lol. Thank you :)
