How to double log since Nuke Day

I used to log in two accounts on the same world using rsbuddy like it was nothing. Now im trying out different clients, and doing different things, but I cant seem to double log every single time. I need one account to be continuously logged, and one log in and out.

 

you have to open up to rs screens at once,then minimize one,get them about to login to the same world,have world selected,minimize once then click play now on the minimized one,then as quick as possible on the other one

 

Yeah, what fame said, just hit login at the same time

 

use the official, downloadable runescape client

 

I need one account to be continuously logged in while another logs in and out, so syncing it doesn't work. Also the official rs client didn't seem to work with multi logging for me.

 

You are unable to log in and out with another account logged in on the same world without logging out on the second account to log both back in at the same time to my knowledge.

 

We have a thread with answers here.
