Why don't we do this?

If we can make a Autoloot in Realm Relay, why can't we make a Autoloot in a seperate client?
Realm Relay refuses to work at all for me, so I really want/need a Autoloot with Nilly's Client or something.

Have you read all the steps to get RR to work?
Have you read the help threads?
Have you used the search feature to find out you're problem?

So you're requesting autoloot to be a mod for mod selector or Nilly's in-game mod selector?
Or both

I've tried all the things you listed and both.
