You can't upgrade all 6 plots with Helpers, if you try, then it won't let you choose any option or cancel and you have to restart the game. Atleast there was autosave.
Oh shoot, thanks for letting me know. It had been working, but I then tried to 'improve' things so something must've been cursed... I'm glad the autosave came in handy and that you like the game's concept even if it is rough. :)
