Was clicking through the tabs on the terminal looking for the one that should have the messages from the program I'd run, to make sure it was done and worked OK. Couldn't find what I expected to see, just a bunch of gibberish errors. Uh oh. Except that was just bullshit warnings from the good old Free And Gratis Graphic Operation Toolkit or whatever it's called that I'd been using, and the reason I couldn't find the output I was looking for was simply that I had never actually run the script in the first place...
this is the first time we've heard the Free And Gratis Graphic Operation Toolkit as a name for the bad open sores image editor, and it fucking slayed us, thanks
(ETA: somehow we missed it when @DecayWTF posted it)
