Purpose of Entity Owner copy?
What does this do?
It copies entity ownership (ownerid), requested by nivex. May be useful for some plugins as well or if you want to reset ownership

Oh. Okay. I thought it might put the  save under the ownerid.

I'd like to run this on my build server. But everyone will most likely just save their build as /copy base

I'd sent you a message about a custom build to prevent overwriting save names. If you're interested let me know.

It's just a concept. I'm sure you have a better idea of what to do.

"EntityOwner (true/false)": false
But it still copy OwnersID
