karoschmitz lol no :D This is not how it works :) this is programming, not some magic spell with limited impact :)) Though I agree they could have chosen better wording. Then again, people that do communications likely have little clue what they are talking about.
All they meant that it's impossible to fix what is already broken in your old saves. And this is true. The files that handles pictures are just empty, you can check it yourself with SimsStudio. There is no fix that could restore their connection to the right textures. But if the bug that severs said connections is fixed, it will affect the whole game - all future pictures, no matter in what save they will be made.
rostsit their mistake, their bug, their problem. They break the game, they repair it.
