Its a bug that is effecting remote control as well.
I need to make a ticket about it, when I get home ill explain a work around.
Alright next time you can not see your clients and its trying to connect try this...
1. Go to advanced mode (top right dropdown box)
2. On the left you will either see a location or not. (blue box)
If something is there just remove it by pressing remove at the bottom (red box)
If nothing was there then go ahead and add a new host, by pressing add.
3. You will now see this window.
In the name, type in anything you want like "Cookie" or "Chris is awesome".
Then in the IP address type in localhost
does not work, then go ahead and repeat the steps and try with 127.0.0.1
