The answer to the question of why Boo Vault's last harvest was 14 days ago is likely due to the fact that the vault could have been retired. However, to confirm this, one can check when the last vault harvest occurred by following the steps outlined in Answer 1. Specifically, one can open the vault page in the UI, find the "Last Harvest" section (top right), and then open the Strategy module and click the "Strategy Address". From there, one can open the chain's explorer and go to the "Events" tab to find the "StratHarvest" transactions and deduct the frequency from that. This should provide the answer to the question of when the last vault harvest occurred.
