Lost all my data in restart despite CPU upgrade and persistent space

Hi,
So I logged in this morning to work on flowise in my space and got a message that I needed to restart my space due to inactivity - ok, maybe I haven’t used it for a week.

Despite paying for a CPU upgrade and a persistent space I’ve lost all my chatflows :frowning: Is there anyway of retrieving my data and preventing it from happening again??
Thanks
Andy
