Basically, title. When my farmer sleeps, her to-do list disappears from her phone and I have to recheck all the boxes for my WIP buildings and such to track them, for every day. I've manually been rechecking them for about four in-game days now.
I know this was a previous issue, but I have not been able to replicate it during the current version. The to-do list should persist during sleep, even if you close the game and reload later it stays onscreen.
