A closed month is locked, and the bank import and possible duplicates are on Transactions
Once you close a month, its entries stay as they were closed: adding one, changing or deleting one, ticking it Cleared, attaching a receipt, importing a bank file into the month or fixing a possible duplicate in it is refused with “September 2026 is closed. Reopen it on the Overview to change this.” and a link that reopens it — and once it is reopened, the same change goes through with nothing to tick. This replaces the tick that let a change to a month already reported to the board save anyway. A month the board got a report for before you closed it says so beside Save and Add Entry, and asks nothing. On Transactions each line has a Mark Cleared button beside its status; Import a Bank File opens a page of its own that asks which account the file is from, and the import lands on the month it filled, saying what it brought in. Possible duplicates are listed on Transactions too, and the dashboard’s line opens them there. Add It, on a Reconcile statement that is off, adds the missing entry to that account and brings you back to the statement.
