My current sim will not go to work (and there's no option to 'go to work')

Hey there!

I just had this issue on my PC and spent more than 4 hours troubleshooting. In the end it was the save file that I had downloaded that was "too advanced" (had packs I don't own) and thus blocked any Sim with a new job (not the ones who already had jobs on the save file) from going to work. Had to revert to an old version for the bug to disappear.
