Is there a CLI command to turn on Auto Replant? If not how do you turn on this feature via commands? We are running a server to which I am an admin but my character does not have admin rights. So I was going to turn it on through my server account if I could. Thank you for any information here.

No, there aren't any CLI command in Straw Golem and I'm not going to implement them. If you have admin privileges, you may be able to edit the strawgolem.cfg file in your server's config folder, changing the line B:replantEnabled=false to B:replantEnabled=true, then restart the server.
