Product: The Sims 4
Platform: Xbox One
Which language are you playing the game in? English
How often does the bug occur? All of the time.
What is your current game version number? 1.15.2.2300
What expansions, game packs, and stuff packs do you have installed? Animal Hats, Cats & Dogs, Kitchen Stuff, Dine Out, Get Famous, Get to Work, Laundry Day, Life of the Party, Parenthood, Patio Stuff, Seasons, Spooky Stuff, Toddler Stuff, Up All Night, and Vampires.
Steps: How can we find the bug ourselves? 1) Have a Sim step into the spotlight and progress enough to receive a quirk slot. 2) Acquire a quirk. 3) Purchase "Quirk B Gone" from the reward store. 4) Have said Sim drink the potion and remove the quirk. (The bug CAN be repeated and all the "unlisted" quirks will stack)
What happens when the bug occurs? The removed quirk's moodlets and mannerisms are still apparent in the Sim. I.E, a Sim will still get the associated Angry and Sad moodlets after the "Juice Enthusiast" quirk has been removed and will frequently attempt to make drinks when in autonomy. The bug also persists if the Sim "Quits the Spotlight".
What do you expect to see? Fixed so only the Earned Quirks in the Fame Info tab should effect a Sim, not all of the past quirks taken and removed in the past.
Have you installed any customization with the game, e.g. Custom Content or Mods? No. No cheats ever used either.
Did this issue appear after a specific patch or change you made to your system? Unsure. After purchasing Get Famous, I don't recall any updates from then up until the bug. Pretty sure this is a glitch with the expansion itself.
Xbox One user here, confirming it here as well.
I usually don't post on threads, but this problem is making it rather annoying to play on my main household; Speaking up to have this fixed soon.
I want to emphasize that the deleted quirks STACK! Meaning even though I got rid of Juice Enthusiast, No Touching, and Vein Street, ALL of their moodlets and behaviors still show.
In theory, you could continuously glitch until you have ALL quirks on a Sim, if you're interested in such a handicap.
If it's of any help, here's a little more info about the Sim being effected the harshest and some screenshots of it happening.
