I had an aspx page in SharePoint sitepages folder. In that page I was linking to a CSS file in Site Assets. I renamed that file and the ASPX page updated the link automatically for me. That's cool, but when I deleted that file and added a new one with the same name, it didn't go back to the old name?
What's happening here, why is SharePoint modifying my files for me without keeping track of the change in the version history?
