Once, you could wish to Become Enemies with a child. This will no longer happen, and fish will not be duplicated in your fridge when moving homes. People will no longer receive a wish to skinny dip with mummies, and you can no longer Try For Baby with the Grim Reaper. Pregnant women can no longer "brawl." There used to be an issue that caused relationships to break when traveling to Egypt, China, or France, and one that made people disappear from the world when exiting the carpool on their way to work. Once, you might have walked on water to view paintings placed on swimming pool walls -- not anymore. If you are on fire, you will no longer be forced to attend graduation before you can put yourself out. Should you choose to skip class activities or lecture halls, your needs will not be frozen. We have also fixed an issue that could cause a teen to be trapped in a child's body when travelling to the future at the exact moment of a birthday.
