I doubt there's an answer to this, but maybe someone can suggest a solution.
I've always used a workaround to mimic a double entry system by using a clearing account to which I post all entries. Today one of my retirement accounts popped up and every single entry going back years had been changed to 12/31/2024. Every explanation and entry had been cleared out; only balances—now re-dated to 12/31/2024 were left in the detailed account. Adjusting the account to yesterday's date was no longer possible.
How on earth did this happen? All of the other accounts similar to this one (my wife and I have 5-6 retirement accounts) were unaffected and could be updated as they always had been.
I can't imagine how to retrieve the data in this account easily. It's not an Excel spreadsheet where it's possible to back up to a previous version when you make a mistake. The last time I backed up the accounts was about 2 months ago, but if I go back to that date I have to painstakingly re-input everything since that backup. Poor planning admittedly, but is there an easier way to fix the one account that's apparently erased years of updates? How did Quicken even do that???
