You should do one for the office zones!

Thanks for explaining the formula! I'm sure it's a bug, feel like I fulfill all those and everyone else in my city is so happy! Industry always near 100%. Ah, I don't have Financial DLC either, sounds weird.

@livingstone
Office Happiness formula is as follows.
1. 15 pts for Workers' Happiness which is an average of Health and Wellbeing.
2. 40 pts for filling up the workplaces.
3. 20 pts for lack of Major problems.
4. 25 pts for lack of any problems.
Totals to 100. Then there are some minor tax adjustments, you can gain/loss few points here.
The biggest weird thing is that Financial Specialisation has a cap of 85% of the total happiness. If you have a lot Financial Specs districts, then total happiness might get a hit.
I don't have this DLC, so I have no idea why they would limit Financial Specs this way. Is there any game reason that would explain that?

After a bit of googling seems it's a known bug with the game since the P&P update - office happiness dropping from 90s to 70s - but CO aren't addressing it. Seems to be affecting non-windows users.

@infixo Thanks for answering! It was actually ShowIt2 that made me think it was a worker issue. I often have a happy face for services but unhappy for education, and the building has overeducated workers. Maybe it's an issue of just generally not having enough employees? I use Realistic Population mod so office demand is very low and citywide I have more jobs available than people employed! PS just activated this mod and it works a treat! 84>93% Great for improving pedestrian zone boost...

@livingstone Thank you :) Imo, having overeducated workers is not an issue. The game usually calculates average education level, and it is always "the higher the better". For offices it is more difficult to satisfy "service coverage". Check your average Offices Level, if many cannot go to L2 then it is probably "to few services". You can also use my ShowIt2 mod to check which services are missing.

This looks great! Wow you've done deep analytics to work out the problem. For me it's offices that always have low happiness - in the 70s. I THINK it's beacuse I have the "prefer higher education" policy and everyone is highly educated, so even though the offices get lots of workers, they are not at the right levels to satisfy office happiness requirement. I wonder if there is a fix for that?

@dimasik38ru Probably because a Steam tag is missing. That doesn't mean the mod is not working. Have you tried it?

Why does the game display a message about the incompatibility of the mod with the game version 1.15.1-f4?

@dimasik38ru Can you pls elaborate?

not works with game v.1.15.1-f4

Works as advertised, thank you very much!
