Granite Falls has no Lots and I can't Play It

I think you're assuming that the issue I'm having is that the lots themselves are just vacant as though they've been bulldozed. But actually, my problem is much worse than that.

There is no option to go into build mode in granite falls in any of my active save-games.

There are no lots to click, no UI dialogue that pops up for me to select 'build' as an option, and my sims can't even travel to one of the lots so I can backdoor my way into putting lots down using bb.enablefreebuild, the save simply doesn't register that there are lot zones in granite falls.
