has anyone ever had an issue when sending out emails using a saved search "when records are created/updated" where you get 2x emails instead of 1? Could it be a script interaction issue (for example there are multiple afterSubmit scripts running on the WO) or something else? The "send update" checkbox is also checked off as well as the "send recent changes"

I could see where an after submit might trigger it a second time

I think this is it
