What happens if I remove values from a custom field
So I have a custom field that has a list of buildings on campus. The list is just a name of each building separated by commas. It is a Single Select field. I want to remove one from the list. What will happen to the tickets that have that building chosen? Is the data then just gone from those tickets? If it removes that value from the ticket will it be detected as a change and then send a bunch of emails out to people with closed tickets?
Thanks for the help!
