Crinrict, I tried again today after the new patch, it still doesn't work for me, only it's even worse.
Instead of not getting paid I get prompted to name the Video Game when it's finished. I enter a name, and then nothing really happens. When I go back to the programming menu there's still an option to continue work on my video game, which immediately prompts me again to name the game, with the same results. No matter what I enter (or don't enter) it doesn't let me finish the game.
I tried completely removing everything from my Sims 4/Mods folder as you suggested, and creating a 100% randomized sim to test this out with. It still had the same results, unable to name and finish a video game.
Everything else in my Sims 4 games seems to work just fine, it's only making Video Games that I'm having this trouble.
That said, I can't say I'm too surprised you didn't have this issue Crinrict. I couldn't find anyone else talking about it when I googled the problem. I'm wondering if something is somehow corrupted with my installation. I've occasionally run into weird bugs over the years in other games that can only be fixed by a reinstall.
