Hi guys,
since SonyaYU does not want to give a list of what object you should use for each career, I dig into the game code with the help of a kind user and I was able to extract the following list of objects or actions that give performance for each career.

This list should be clear enough to you if you are familiar with the game.
Note that also some modded items (like sax and flute) are listed, I guess this is because of the "mod integration" feature.

I'll soon test a lot this list by playing the game, to be sure it is completely correct.

@SonyaYU Please update the mod description with the list of objects that XsauroxPlayer has so kindly spent time and effort into compiling. This is something that you should have done upon initial upload and when asked.

As I've spent time and effort including into the game itself and emphasized said feature (and yes, it is, in fact, legible, it's very unlikely and uncommon to have eyes worse than mine that are still usable and I can read it, granted the game's UI scaling isn't ideal, but any glitchiness is very minor)?

Regardless, I've included the list as a temporary collection with a note that not everything is proven to reliably give performance and is a subject to change.

Thanks for updating the description with the list!

Hello. I adore UC mod. I've been playing with Zerbu's mod for a long time. I remember his problems. First of all police officers did not improve their productivity when they wrote a surveillance report. SecondlyThere was no reward for happiness points for children, which stops a decrease in productivity if the child does not interact with objects.There is a reward for adults and teenagers. Could you make a function that will stop the degradation in such cases?

What Lot's Event file is used for if I'm using this mod for the first time (no previous original Zerbu download) ?

I like your mod very much, but when I choose a workplace and click the wall to add the career, the menu only shows many careers without their lots. I mean if a career has many workplaces but in your menu they have no differences. Can you fix that issue? Or could you tell me how to remove the New menu function for assigning careers to lots from your newest version mod?

So great that you have expanded the list of items that increanse productivity, thank you! Unfortunately, when I play open school I have some problems unlike the original mod. For example, if a Sim autonomously goes to the ballet barre and chin up bar, their school scores will increase, but the skill itself will not increase and the hygiene level will not decrease. If I direct it myself, then the Sim increases the skill and his hygiene drops, but his grades also drop.
