It works fine on the home lot. I completely uninstalled everything and removed the entire Sims 4 folder that was left behind in the documents folder. I first tried it out on a completely fresh install, but it didn't make a difference, so I then put my saved games back. The only thing I've restored since the install is my "saves" folder. I did test several different fridges on the retail lot, but none seem to add any time to the new items.
*edit* I tried something else. I copied the home lot and retail lot and started a new game with a random sim. I cheated in the money, and after milking the cows and collecting eggs I tried it again. It worked this way. The time left went up to over 17 days. I'm worried that something is getting corrupted over time because it took awhile before I was able to afford the retail lot before. The only other difference was that my family was witches, and the new sim was "normal". I didn't want to start over, and since no CC or mods were involved, I'm worried this would happen again eventually. I was also getting a lot of other glitches that I could ignore more easily.
