I found no eggplants or corn in my world when playing with this mod,
so I tried placing Cultural Delights' wild crop patches via commands to test if they could be generated in the first place, and then I discovered that placing specifically the wild eggplant patch feature does nothing.
After messing around with the mod's files I found the reason why:

In the file "culturaldelights\worldgen\configured_feature\patch_wild_eggplants.json", line 11, it says:

"Name": "culturaldelights:wild_eggplant",

which is actually incorrect, and after I replaced it with

"Name": "culturaldelights:wild_eggplants",

The eggplant patches started generating normally.

patch_wild_eggplants.json

Shesh, ill fix

Ah i see, thank you

I have forked your repo and fixed this and some more stuff. Everything seems to work properly now.
