During the spring, one of the Green Bean crops, though watered, like all other, failed to climb up a stage but was still watered in the morning. That particular crop happened to not die in the first day of summer. Out of curiosity, I watered it like normal and it died on day 2. In the morning of day 2 I noticed two other crops, thought watered, failed to grow and were still watered, a melon and a blueberry. - EDIT: The next day, another two, different tiles, didn't grow and remained watered. This can really mess up schedules.
