Did we delete a card?

A customer’s card vanished overnight. Did we delete it?

Exploring · 14 tool uses└ Done

Fizzy didn’t delete it.

It moved to Not Now after 7 days with no activity (Acme’s setting; 30 is the default). The card and its history are kept.

A RECENT CHANGE MAY MATTER

On 4 Oct, Rosa Gutierrez fixed a bug that could stall the hourly check. Once that fix is live, overdue cards all move at once, which can look like cards vanishing overnight.

I can’t tell from the code whether the fix has shipped yet, so this is unconfirmed.

REPLY TO CUSTOMER

Copy

Hi Mia, we haven’t deleted your card. Cards on your board move to Not Now after 7 days without activity, so that’s where it is. Move it back to any column and it’ll be just as you left it.

Note: Acme’s board is set to 7 days. The default is 30.

Nothing’s lost. It was parked after 7 days with no activity. It can be moved back in a click.
