A strong sense of smell wouldn't mean they'll chase everything they smell. They can smell things like trees but don't chase trees (at least they shouldn't, but they do in this game...

). Just being able to smell something doesn't mean they would have any interest in it. They smell each other but don't attack each other. Rotten meat doesn't attract them even though that should have a very strong smell. So for them to target a specific smell, it should mean that it is something they would eat. Meat is a common thing for zombies in books/shows (mostly raw meat and fresh kills, but any meat is acceptable). But fruit and vegetables? I'm not sure that I've ever seen a show or book where zombies were scavengers, eating everything they find. They aren't looting dumpsters and trash cans. They aren't eating plants that are growing. They are targeting living people and fresh kills/raw meat. If they aren't scavengers (animals/creatures that will eat basically anything), then for a smell to attract them, it should be something they'd actually be interested in. I can't see that with fruits and vegetables. They aren't eating your farms even if your farms aren't protected. At least, not unless they are in demolition mode next to them. They aren't attracted to the farms either. So why would they be attracted to your vegetable or fruit food?
In the end, I don't really care. If it remains as it is, I'll disable it. If they improve it, then it will depend on what they do to improve it. If they don't want to hear what people think about it, and what I believe are valid points, then so be it.
