I was reading the other day that new wilderness areas like saltmarsh and isle of dread have 'inactive' mobs to reduce lag yet they have tons of 'active' frogs, bats, squirels etc. Would they be less laggy if they didn't have such pointless creatures? Pointless in the matter of 'active' and taking up 'memory', not pointless in the sense of 'adding' to the world.
Why can I target a frog from even beyond my sight but monsters I have to go right up to?
