SIms 4 Island Living "OFF the grid" is really confusing me!!!!
SO I didn't realize there were lots that were off the grid on the island... I went through building a REALLY cool home for the Sim/Mermaid I had just created... when I placed a light in the! kitchen, ...
It's probably because the home was built on a lot with the off the grid lot trait and it saves it with the trait. Did you open up the info for the lot and remove the trait?
