I had a similar issue. I tried going into "Town Edit" Mode and place the premade bakery that comes with the set. I made some pie at the bakery but my sim would walk over and place the item on the counter then i couldnt pick it up, put it in my inventory or even move the item. Later after several tries i tried making a home bakery. This didn't work out because no one would come unless I called them via smart phone to come over and it was just annoying having people walk around my house then i would have to ask everyone to leave. I hope they figure these issues out : /
