I noticed something really odd yesterday on my sandbox.
I had just done a GUI update, all went well. When it was done it showed the blue “Upgrade to the latest version” button to the right, but when I clicked the git compare button in the left column, git showed "There isn’t anything to compare.
Was this a browser cache issue, or did something or other make a “Jump to the left, then a step to the right” on me?
Not long after that there were some new commits, and things went back to normal.
I’m not sure exactly what happened, after all, time is fleeting, but I don’t remember madness taking it’s toll.
