Is the fruit clearing on the start of each day still current, as I'm sure my fruit was on the ground longer than a day. I read the knowledge article and it didn't mention fruit clearing after a day.
Fruit trees take several days to produce fruit, since they have to mature, produce flowers, and produce ripe fruit. The fruit is not harvestable until it falls to the ground. If you want to rely on fruit trees as your only source of food, you will need to plant a few trees each day for several days in order to make sure that fruit ripens and falls every day.
