Product: The Sims 4
Platform: PC
Which language are you playing the game in? Polish
How often does the bug occur? Always (100%), tested extensively on about five books including rereading and browsing them for hours.
What is your current game version number? 1.55.105.1020
What expansions, game packs, and stuff packs do you have installed? All expansions, all game packs including Realm of Magic, stuff packs: Cool Kitchen Stuff, Spooky Stuff, Movie Hangout Stuff, Romantic Garden Stuff, Kids Room Stuff, Backyard Stuff, Vintage Glamour Stuff, Bowling Night Stuff, Toddler Stuff, Laundry Day Stuff; free packs: Holiday Celebration, Grim's Ghoulish Guitar
Steps: How can we find the bug ourselves? While having the spellcaster perk "Knowledge Is Magic" which makes reading books faster and having Renaissance Sim aspiration on Prudent Student level active and/or Read a Book whim. Books belonged to the active Sim from his bookshelf in his house Daisy Hovel in Willow Creek, some were purchased others came with the shelf. They were read in Sim's house. The Sim in question was made a spellcaster in CAS. Knowledge is Magic was his first perk taken and alongside hje also had perks Mote Hound and Insightful Eye. The books were all non-fiction, none were spell books.
What happens when the bug occurs? Books read does not register for neither Read a Book whim nor Renaissance Sim aspiration first requirement Finish Reading 3 Books.
What do you expect to see? Books read registering for both Read a Book whim and Renaissance Sim aspiration Finish Reading 3 Books requirement. And when I removed the Knowledge is Magic perk with a potion a new book read did register for the Finish Reading 3 Books requirement (not tested for the whim as I couldn't get it again for now).
Have you installed any customization with the game, e.g. Custom Content or Mods? No.
Did this issue appear after a specific patch or change you made to your system? No.
@daWhiteBAG Additional note: Reading a book registered correctly for the Scientist career track daily task at work while having Knowledge is Power perk. The very same book did not register for the aspiration.
