Rank 2: Process
I logged in my cloud account and a message was shown to me telling that I would have only one free organization. So as I had two, I looked in both organizations what projects were in them.
In one organization I had two projects listed, in the other one I had none. I had checked three times before delete the empty organization. Then I hit delete button and OK. So I came back to the home page, and my organization previously with two projects now has only one project. Somehow, after delete that empty organization, one project was deleted together.
If I had made the mistake of deleting the wrong organization, I would have lost two projects, not just one.
Maybe in the past, I had transferred the project from this previous organization (now empty) to the new organization (with two projects). And I believe so.
