As title said I have accidentally overwritten a session in session manager with 400 plus tabs. It was not deleted but simply i clicked on the session and saved new tabs and overwrote it. Since i have not opened that session in a few weeks there are no other copies in the old or deleted sessions but just a few minutes ago all the tabs were there. How would i go about finding it if possible?

Is it really that simple? There are no checks to protect against that? I was wondering if the sessionstore held any promise? It was iterally there just a few hours ago how can it just be gone into the netherworld forever?
