Ok,. I bet it's definitely something wrong here.
I moved in a house next to the "problem property". Doing so made the eco-footprint drop from "green" to "neutral" - in both houses. Logically, the effect is no longer visible on "manage worlds" page. Cheers, the problem was gone on the problem property. Ah, wait. Only for one sim day. While the eco-footprint is still neutral and the effect is still no longer been shown in manage worlds, it's present again in the problem property (and only there, the other house is free of it). When zooming out, it is that massive, that only a white screen is viisible. APU Fan is speeding up, fortunately after cleaning and applying new thermal grease, console is no longer shutting down due to overheating.
Bulldozing the property does remove the effect immedaiately. Replacing it from the gallery does bring it back.
I didn't make a video today, since obviously nobody cares (zero views on the other two, I assume EA is busy w/ counting money).
