Classic is a hardcoded option and touches both critter spawns and mapgen; Mundane, being a mod, is a JSON blacklist, so no, it just stops critters from spawning, rather than affecting mapgen.[/quote]
I think you may be mistaken. I have now built multiple worlds with only the Mundane mod, and every other setting left at the defaults, and not seen a mall once. I then tried without the mod and got a mall. Not complaining, just not sure if that is the intended behavior.[/quote]
If so, that’s a bug. Thanks.
