and it's making it difficult for me to review logs. I have tried disabling Enderman block picking, but for some reason using the /zone flag command while in edit mode doesn't do anything. Upon further inspection, I noticed that the yamls lack an endermenpickblock flag at all. Disabling enderman spawning altogether obviously stops this, but I want endermen to spawn normally.
