To recreate: - Set WhenLostChargeReplacementFee ON, WhenLostForgiveFine ON - Set you refund lost item value to EITHER refund lost fee and charge a new overdue fine OR refund lost fee and restore overdue fine - check an item out with a due date in the past, run the fines cron - mark the item lost, confirm the overdue fine is forgiven and a lost fee is applied - set checkin to Fine Free mode and check the item in - confirm your lost fee is gone and your overdue is back If the item is checked in on Fine Free mode, the fine should not come back. Or at least that should be a configurable option via a syspref. We have libraries set Fine Free on for all checkouts for amnesty periods. This sort of return of long-lost items is exactly what they're trying to incentivize with such a program.
