enemies dont spawn within workbench radius?

Work benches, camp fires, torches, fermenter, kilns, and so on create a 20 meter no spawn zone around them. (Simple structure parts like walls and roofs do not) It's why you want the objects spread out around your base or walls or fortifications are useless. Like if you have a wall a torch ever 30m or so along the inside is a good idea as it also creates a buffer zone between the wall and potential spawns.
Note, these prevent spawns within 20m but do not prevent mobs walking in after spawning if they have an open path.
