(I'll come back to this when I can recreate it consistently.)
When using Tab Groups the left-most tab in the default group of a Profile can sometimes become "unloaded" by Safari. Likely due to memory management. I believe this makes that tab invisible to Switcheroo as the AppleScript cycles through windows? Which forces Switcheroo to open a new Window.
To restore functionality you need to activate the left-most tab in the default group of the Profile and then Switcheroo can see it again.
