This is an issue I had for years. Even though my farm reset to level 1, my farm layout doesn't reflect that. It's still exactly how I left it. Which means when I'm told to harvest tomatoes for the tutorial, there are NO tomatoes to harvest. Clicking the plots brings up the unwither window and clicking does NOTHING.
There must be a fix for this. Compared to everyone else's experiences being reset to level 1, this is highly unusual. I asked Zynga directly for help years ago when this first happened, I got no help whatsoever.
