I noticed that a label that we use in our project fairly frequently has completely disappeared over the last two weeks. It is not selectable from the drop down when you start typing in the "labels" field, and there are no tickets that currently exist with the label. It's almost like it never existed.
BUT! We can look into past tickets that we know had the label, and in the history, we can verify the date that label was added. However, there's no update that the label was removed, even though that label is no longer on the ticket.
We've looked through our logs, and there were no bulk changes made, and no changes have really ever been made to labels in our Jira instance, beyond various projects creating new ones here and there.
What could cause this? We did recently convert Epics to Features, but there was nothing touched with Labels, and so far, this is the only label that has gone missing.
