Error appears in log [Worker-Main-9/WARN] [net.minecraft.world.level.levelgen.structure.pools.JigsawPlacement/]: Empty or non-existent pool: minecraft:
How can I find out the reason for this error? And if mods do it, then which mod gives this error? Some lines show it's dungeons-arise, other times it's empty.
Does this error reduce the amount of content? I don't know
thanks for the help
