A new introduction has been added called "exchange names" this was requested!
Fixed the party invite issue. Only sims with homes can invite you to parties at their home. It will no longer be a random residential lot but their actual home. If you don't have a certain venue placed or available for your game you should not be invited to a party involving it.
The cat cafe invite will spawn cats and not humans.
The height slider has been removed.
The goodbye notifications error is now fixed.
Face masks should no longer show up when purchasing seeds.
The architect error has been fixed.
The old memory system has officially been deleted.
Party invites have been toned down. However, any already scheduled invites will still flow through since they are already scheduled.
There is now a lower chance of having to poop. (5/100 chance)
Call to chores is now "Gather household" so it should just make everyone gather to that area.
Call to bed is now "Call to the bedroom" this interaction will drain the sims energy but will not "force" them to sleep
Added thought popups for sims!
New Memory System
Your sims will now have memories of doing the following:
Graduating
Going Out
Eating
Fires
Birthdays
Promotions
Getting Fired
First Kiss
First Woohoo
Pregnancy
Giving Birth
Death (Pet, Family, Friends)
Witnessing Death
Divorced Parents
Fighting
Getting Caught Cheating
Wohooing
Getting Married
Peeing Self
Showering
Cleaning Up
Dates
Break Ups
New Relationships
Getting Engaged

Some options are only available for certain traits for example this one is available for evil sims.
Will more be added?
I hope to expand this list with further updates but figured this is a good enough start.
What does the new memory system do?
Your sim will remember things that have happened to them which will either be short or long memories. They will get a buff/moodlet about it as long as they have the memory and will be able to talk about it with others. You might notice some moodlet/buffs when talking about certain things and even some popups.
Are sentiments added?
I am new to sentiments and have only added one to this update which is how children respond to parents' divorce. Until I get to learn more about them coding wise I will not be adding more.
Will there be different responses?
I have started adding different responses to memories based on chance (for example: 50/50 chance that a first kiss will be bad or good) and on traits. This system is new so it will require more time to grow and develop.
MAC USERS: For some reason, the files are locked upon download so you will have to go in manually to set them to 'Read & Write' before you start your game with this mod. The reason/cause is currently unknown.
Example for Mac users:

New Strings:
KS - SOL Memory System (Personality folder)
KS - SOL Memory Convo & Thoughts (Personality folder)
I am so excited to use the new update! I just want to say thank you so much for all of your hard work! I couldn't play the game without SOL now! Youre amazing ❤
tysm <3
I always look forward to an SOL update !!! thank you queen 🥰
i went on twitter to check if there was new update yet and i almost screamed when i saw it lol. this literally made my day 😅🥰
So excited this is updated! I am new to the mod game, but been playing the sims for forever. Your mods are the only ones I have and love!
Hi, I can't seem to make this work on Mac. I've updated all files to Read & Write permission. When I click on a sim, the pie does not show up.
I have this issue but on windows. It worked fine the first time and then when I reopened the game, I can't click on the selected sim...
@Courtney Rush I don't remember how I fixed this, but I just kept removing and re-adding the mod and then suddenly it worked.
I also have the same issue, I cannot click on the selected sim and to other sims to interact. It worked for a while but when I played again- it just won't work anymore thus I sadly have to remove it from the mods folder.
same
Thank you for the update! Quick question: are the melanin overlays still compatible?
Anyone else's Sims getting sad for no reason now? They'll literally be fine, with no feelings or mood then will suddenly become sad without explanation.
Mac user here. Everything worked fine and I didn‘t have to manually change the permissions.
Mac user too, and same
I don't know if its just me but when I try to select a specific personality I click on the sim, go to the SOL menu, click control panel, personality modifier, pick sims personality but nothing comes up and it gives my sim a random personality. I've updated it, and even tried repairing my game but it still does the same thing. Am I just being and idiot and missing something?
I have the same problem
Would you consider to make pee puddles yellow? To make it more realistic.
I am receiving a few errors with the Memory System. Still checking if it's a conflict with other mods but I'm attaching the Better Exceptions report here.
I'm think Im having the same issue. I am unable to click on my sim and am getting the same error report from mccc. I've checked for conflict between Memory System and my other mods to some success. It seems to run fine as long as I dont have the SOL Skincare, Sickness, or Health and Beauty systems installed. Those three cause a similar issue and error report if I try to run them in the game, even without memory system installed. All the other SOL mods are running fine though 😊
I'm having the same issue! Is there a fix now?
I don't know if it only happens to me but mccc and scubumbo's error notifier keep identifying errors in SOL, particularly in drama and personality modules. It doesn't cause any errors, I'm just a perfectionist so I hate not having everything organised. I'll understand if you won't look into that but I'll also be thankful if you do. I can provide a bit more info if you'll need any. Love!
I'm having some issues with the memory system package and I'm not sure why but I see I'm not the only one. MCCC says it detected an exception and when checking what was wrong on the log it seems to be a problem with an attribute error, the last caught exception is in brackets (Exception during call to test method on <class 'sims4.tuning.instances.Kawaiistacie_SOLMemorySystem_BuffMemorySystem/3320736193'> (AttributeError: 'NoneType' object has no attribute 'matches_bit')) It's a pity since the memory system is a great addition to the mod and I had to take it out as it was freezing my game and being quite buggy. I'm not sure where I can send an issue like this so decided to place it in the comments here.
I did a clean up my whole mods folder so I know I don't have any old files. It's either conflicting with other mods (I have quite a few) or there is a coding error inside the update. though you are probably looking into this already! Nonetheless, this mod is absolutely amazing. Definitely a must have!
I'm having the same problem in my game. I cleaned up my mods folder and re-downloaded the game and there was no luck.
I've just written a comment about it!
I have a problem
I cant click on the toilet anymore to see the sims ferfility
Não sei o que acontece, pois tem uma tal de vitamina D que fica diminuindo deixando os sims exaustos e manda tomar sol, mas mesmo tomando sol não sobe. Alguém pode me ajudar?
I actually really enjoyed the height slider :( Do you think this is something that you can re-add to future updates as an optional addition.
I cannot change to "Read & Write" thats not an option
