I'm using 1.19 here.

Can you check if there's a way to respect rules from other mods like https://legacy.curseforge.com/minecraft/mc-mods/brazier/

That mod adds a structure to prevent hostile mob spawns within a radius, but your mod seems to override that. Would be nice to have both working.

Currently tested with majruszs-difficulty-fabric-1.19.2-1.9.9-backport.1.jar
