Product: The Sims 4
Platform: PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? Latest + Spellcaster DLC downloaded.
What expansions, game packs, and stuff packs do you have installed? Spell Caster DLC.
Steps: It is very simple to trigger the bug, simply have your Sims in the Freelancer career with Writing select as his goal in life, and start writing a book. Once you travel with that Sim or any Sim of that household (including when they go to work or school) try to get the Sim to resume or start writing a new piece. It will not work. Make sure you have your Sim selected as a spell-caster, I am not sure if the threads of the Sim personality can trigger it but so far it happens almost every single time with me, when my Sim goal is to be a Writer. I also had that issue when my Sim aim was to become the most powerful Spellcaster (the one from the DLC).
What happens when the bug occurs? When you try to start writing or resume one, the icon for writing on the PC queued up for a bit and then immediately is cancelled by the Sim themselves. Not sure why. Sometimes it shows as a black flash-drive as well, not sure what that is but it does happen sometime.
What do you expect to see? A pop up to appeal once the Sim sits on the computer asking for the Book title, or the sim to resume writing already started book.
Have you installed any customisation with the game, e.g. Custom Content or Mods? I did, but this bugs started happening before I installed any mods...
Did this issue appear after a specific patch or change you made to your system? I am not sure about this one, I do remember there was a recent a update on the game, like a week ago or so, but this is the time when I was still learning about the game, so it could have happened after the latest patch or it could have existed before that.
