So I've got SourceTree for Windows, and I've updated it almost whenever it asked. Today I updated SourceTree and it gave me the message "Sourcetree 1.9 will not be updated anymore" and gave me the option to "Go to the download page" or "Open SourceTree (you won't get updates anymore)", as if I had gone out of my way and installed the older version. Now my About shows version 1.9.13.7, though I'm not sure what it was before TBH.
Is this an update bug? What the heck happened here?
