Hi John
She has strawberries planted on those farms which will be ready in less than 6 hours.
Tell her to open her storage and take not of the amount of strawberries she has. Please remember to not take note of the strawberries (large) as those are the ones harvested by others.
When strawberries are ready in one on the farms, then ask her to go there and open her yellow tool box and click in the Farm stats icon, it is located above the clock.
When it is open, set it to Crops, Ready, Now, Current Farm. At the botton she will see 2 options, both need to have a check mark.
Then take not of how many strawberries she should get.
After harvesting that farm, that amount should have been added to her storage total.
If not, please reload the game.
