Buried Campfire Being Lit in Trail Ruin

So... this isn't really a bug, but I found a lit campfire buried deep underground in a trail ruin. A lit campfire. With (for lore implications) no oxygen and has been going for who knows how many hundreds of years. A few players might be confused or annoyed by this, but an unlit campfire would make more sense. Just letting ya'll know. 🙂
