I had the opportunity this afternoon to record a session of ATC where traffic was inbound with approach. Approach logged off and the planes all clumped together. This caused @JoshFly8 to come in sort it out. As you can see some were sent well out of their way just to be able to sort things out.
This is what Joshua saw when he logged in.
Here is the time lapse video which shows it nicely.
And for reference, this is my approach post where I point out the need to spread out as well as other approach items.
