The Sims is a groundbreaking series of life simulation games that have entertained players for over two decades. Each of the 4 mainline Sims games, and their numerous expansion packs, provide players with the tools to create countless different scenarios with their Sims. But sometimes players come across glitches that present them with unintended scenarios.

These glitches usually end up being amusing, but there are also plenty of glitches that are effectively game-breaking. Some of these glitches have yet to be fixed and with continuous updates to The Sims 4, more of these bugs and glitches are sure to be discovered.

10 HILARIOUS: Sims Randomly Get Cloned

In The Sims 2, there is a rare chance that a player's Sim will suddenly get cloned. An identical counterpart to that Sim will spawn, allowing for a Sim to interact with and build a relationship with their clone.

This glitch likely sprouts from another glitch where Sims display a relationship with themselves or even want to become friends with themselves. No character file is created for the clone and it is treated as an object. The clone can simply be deleted using the Moveobjects cheat.

9 GAME-BREAKING: Sims Are Obsessed With Cooking And Baking

Sims being obsessed with cooking or baking is a common glitch in The Sims 4 that has only recently been patched. Sims would be stuck in a loop where they would cook a meal, set it aside without eating it, and then cook another meal.

In a related glitch, Sims may not eat leftovers from the refrigerator, creating an excess supply of food that just goes to waste. Players should be careful because if they do not manually remove their Sims from this cooking loop, it can quickly drain their Simoleons or prevent their Sims from relieving their hunger.

8 HILARIOUS: Sims Have Matching Hair And Teeth Colors

In The Sims 4, there is a glitch that can occur during the Create a Sim process. When using hair swatches with specific hairstyles, such as a bob or dreadlocks, that Sim's teeth may change to the color of the hair swatch.

This change is not just seen in Create a Sim section but is also reflected in gameplay. This glitch is an interesting way to make a Sim stand out, allowing them to deviate from the standard white teeth, instead having yellow, brown, gray, or black-colored teeth.

7 GAME-BREAKING: Toddlers Are Taken Away Because They Can't Fulfill Their Needs

Toddlers were a much-anticipated addition to The Sims 4but their arrival was accompanied by its fair share of glitches and bugs. One of the most frustrating glitches happens when a toddler won't put down their toy or food. This causes the object to be stuck to the toddlers' hands and prevents them from fulfilling their needs.

They won't eat any food given to them, use the potty, or even sleep. When a toddler's needs are not attended to, the game can take away that Sim from the household. This glitch has caused some players to permanently lose their toddler Sims.

6 HILARIOUS: Wrinkled Teens Look Older Than They Are

In The Sims 4, a glitch can give teen Sims crow's feet around their eyes. This can occur when a child Sim ages up to a teen or when players create a teen Sim through the genetics options in Create a Sim. Especially since teens in The Sims 4 are the same height as adult sims, this glitch can make teen Sims look much older than they are.

Usually, crow's feet would only be generated on adult or elder Sims. On the bright side, having a weird old kid hanging around can be pretty funny.

5 GAME-BREAKING: Corrupted Lots Block Off Content To The Players

There is a glitch in The Sims 4 that blocks off content from the game due to corrupted lots. When players encounter a corrupted lot, they will be unable to load the lot. Even replacing the lot with a new one isn't a surefire fix. The Snowy Escape expansion pack is notorious for its issues with the Sutefani Onsen Bathouse lot.

Players will often be unable to travel to the lot, which is how they can take part in Mountain Climb Excursions. The lot being inaccessible essentially blocks players off from a large chunk of the content that they paid for in the expansion pack.

4 HILARIOUS: Peeing In The Toilet Starts A Fire

Seeing as the bladder is one of the basic motives for Sims, toilets are an essential part of any Sim's life. Things can get strange in The Sims 4 when a glitch can cause the toilet to catch on fire when a Sim uses it.

The glitch seems to be related to the Eco Lifestyle expansion pack, as players can upgrade their toilets with a Composting Container that will catch on fire if the compost goes unused. Players without the expansion pack occasionally still experience their Sims starting toilet fires with their pee. Luckily, this fire is harmless and is extinguished when they flush.

3 GAME-BREAKING: Sims Fail University Classes Despite Meeting All Requirements

The Discover University expansion pack for The Sims 4 allows Sims to enroll in university and experience campus life. However, a glitch can severely hinder the university experience for players by having their Sims fail their classes, even if they have met all the requirements to pass.

This glitch can make the work players invest in making their Sims study, do homework, take notes, and raise their skills for a class be for nothing. This, in turn, prevents their Sims from graduating and using their degree for their chosen careers.

2 HILARIOUS: Ghosts Can Take A Taxi To Random Lots

In The Sims 3, each graveyard is populated with ghosts that can leave at night to haunt Sims on other lots. The Ambitions expansion pack can cause a glitch where graveyard ghosts behave in unusual ways.

While ghosts usually rise from their tombstones and leave the graveyard in their own ghostly cars, the glitch can have them take a taxi or random car to another lot. Ghosts will sometimes travel to empty lots and just stand there before vanishing. If players manage to interact with the ghost, that too will cause it to just vanish.

1 GAME-BREAKING: Sims Won't Go To Work Or School

Going to work is integral for a Sim to make the simoleons necessary to live. Meanwhile, going to school is a requirement for all child and teen Sims. There is a glitch in The Sims 4 that prevents Sims from going to work or school. When the time comes for a Sim to leave the house for work or school, the action starts but is never completed.

Even manually making the Sim go to work or school will not work. Sims who don't go to work will not be promoted and may eventually get fired, while Sims who don't go to school will get low grades that affect the career level that they start at.
