Product: The Sims 4
Which language are you playing the game in? Español
How often does the bug occur? Every time (100%)
What is your current game version number? 1.65.77
What expansions, game packs, and stuff packs do you have installed? All of them
Steps: How can we find the bug ourselves? It's kind of hard to reproduce, but here we go. You must have UI Cheats and be able to see the Ecofootprint_lot commodity. That's why Im' sure this is a bug and I think most people don't realize it exist. (it might be the cause for the bar to decay quickly and you're lot going to a neutral state everytime you load the game up.) Build a house with a lot of industrial/green build mode objects. Then, go to live mode and check the ecofootprint value of the lot. Change it with UI Cheats to another number. Travel to another lot and then, go back to the previous lot.
What happens when the bug occurs? When you check the lot ecofootprint commodity, its value will be "stucked" on the value the commodity had prior to your travel. This, obvioulsy, will cause the street ecofootprint to move to another state.
What do you expect to see? The game keeping the lot ecofootprint value that the lot has.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure
So, I've been doing a lot of testing, and I think the problem happens the moment you add a lot of items from Build Mode that has a ecofootprint. To be clearler, I will explain the problem with an example:
I've done lots of testing, without mods and that problems persists. If you don't add any build mode object with a ecofootprint, this doesn't happen, so I can say that is the cause.
