Oceanic Realms incompatibility (Forge 1.20.1)

[KarnivaleFool]

Hello, there is a crash happening with Atmospheric and Oceanic Realms when trying to load a world

The crash can be recreated with 3 mods: Oceanic Realms, Atmospheric, and Blueprint on Forge 1.20.1

The issue seems to appear on versions newer than Oceanic Realms 1.0.6.2-hotfix2

Oceanic Realms officially no longer gets updated so I'm asking here, who knows ?

Thanks for your time ! :)

java.lang.IllegalStateException: Error(s) loading registries:


Errors(s) loading registry minecraft:worldgen/structure_set:

Not a JSON object: null
    at: worldgen/structure_set 'minecraft:worldgen/structure_set/villages.json'
    at: pack 'vanilla'


Errors occurred freezing registries.
These were elements that were referenced, but never defined (or their definition had an error above).

Missing references from the worldgen/structure_set registry: [
    'minecraft:villages'
]

Gonna need to see the full latest.log though it's likely that they're breaking something of ours and we won't be able to fix it

I have little hope but thanks for even considering the issue ! It's likely an Oceanic Realms problem but a man can dream :')

This crash happens when trying to enter the world creation menu:
