Yeah the Rita issue is more than likely people coming straight from rita to thirteen - priority passes if they've been stuck on ride, disabled guests and fastracks all appearing at once. Happens if two rides are close together - if both were working it'd be fine.
Spinball, agreed. Think everyone agrees. Nemesis that picture was caused by someone not actually doing their job properly (let's say, they let 4 fastrack in every 32 queue) over a half hour period that's what was created. NST is fine with fastrack, knowing from experience. SW7 will have same treatment as other rides!
