I have contacted support about this several times and have never had anyone get back to me with a response. When an official declines an assignment, they are asked for a reason, and that reason goes back to the assignor in the resulting email and gets placed in the database. HOWEVER, when an official turns back a game that they have previously accepted, that same reason does not get passed on through the email. It IS, however, stored in the database, because you can look it up in the system through the Declines Report. It seems that this would be easily resolved by making the automated email that is sent out for turnbacks identical to the one that is generated by declines. Seems like this reason field is simply "missing" from the turn back email. Shouldn't this be an easy fix.
Reason for Turnback not listed in email
