The reason why this is a serious glitch is: most of the sims garbage cans DON'T work off the grid. Well, they accept garbage, but the "exterior" trash receptacles aren't bottomless like they are if you're playing a on the grid lot, so eventually they reach capacity and overflow.
The logical progression is to buy the nano can, which converts the digital garbage to energy. Since it can't accept anything, our sims have a nasty lot.
(Also, I am not in love with the nano can's futuristic aesthetic, it' clashes with my OTG castaway look)
