The toddler not eating bug is strange. The child I have currently, as a toddler he ate just fine in their first home. On vacation in Mt Komorebi, he wouldn't eat. Back home again, he ate normally. When I had them move to Mt Komorebi, he ate. I aged him up as soon as he earned Top Notch Toddler, because toddlers are a pain and he had a little sister coming soon. So then his little sister wouldn't eat- until they moved to Evergreen Harbor.
And the project completion thing is also unpredictable. His first project, he completed normally. The next week, he and his mom worked on it for hours, no progress bar, and it never even changed to the next stage. He did earn a lot of Logic for it though.
And a while back there was a bug with self care and day care, where only Hunger would fill up. I had a single mom doing an active career, so she would come home to an utterly miserable toddler every day, and spend the rest of the evening resolving that. Potty, bath, play at least twice, then get the poor kid to bed, by that time it's midnight. At that time, I hadn't discovered UI Cheats Extension.
